java pivot

Method describe behavior of an object. A method is a collection of statements that are group together to perform an operation.

There are three step to define Method:

Syntax:

Declaration of method:

void java_pivot(){

            //body of method

            System.out.println(“ I am java pivot method”);

}

 //program to add two no. using method

public class Methodadd {

    void add(int a,int b){

        int c= a+b;

        System.out.println(c);

    }

    public static void main(String[] args) {

        Methodadd ad = new Methodadd();

        ad.add(10, 12);

    }

   

}

Output:

If you want print pattern like given below:
1
2 6
3 7 10
4 8 11 13
5 9 12 14 15

//program to print pyramid pattern 

package pattern_progrm;

public class Pattern_progrm {

    public static void main(String[] args) {

        int i,j;

        int sum ;

        for(i=1;i<=5;i++){

            sum=i;

            for(j=1;j<=i;j++){ 

                System.out.print(" "+sum);

                sum+=5-j;

            }

            System.out.println();

        }

}

output:

Pattern based exercises are a better  way to understand  nested loops in Java. There are many pattern based exercises and one of them is printing Pyramid pattern code as shown below:

// program to print Pyramid pattern in java

class Pyramid1{

                public static void main(String rgs[]){

                                int i, j,k;

                                for(i=1;i<=5;i++){

                                                for(j=5; j>=i;j--){

                                                                System.out.print(" ");

                                                }

                                                for(k=1;k<=i;k++){

                                                                System.out.print("* ");

                                                }

                                                System.out.println();

                                }

                }

}

output:

//program to print pyramid pattern in java

class Pattern1{

                public static void main(String[] jawed){

                                int i,j;

                                for(i=1;i<=5;i++){

                                                for(j=1;j<=i;j++){

                                                 System.out.print(i);      

                                                }

                                                System.out.println();

                                }

                }

}

Output:

Above given program , if print j then what will be the output:

Let’s see,

class Pattern1{

                public static void main(String[] jawed){

                                int i,j;

                                for(i=1;i<=5;i++){

                                                for(j=1;j<=i;j++){

                                                 System.out.print(j);      

                                                }

                                                System.out.println();

                                }

                }

}

Output:

If want print reverse Pattern then below show the code

class Pattern1_rev{

                public static void main(String[] jawed){

                                int i,j;

                                for(i=5;i>=1;i--){

                                                for(j=1;j<=i;j++){

                                                 System.out.print(i);      

                                                }

                                                System.out.println();

                                }

                }

}

Output:

That's all about how to print Pyramid using Java pattern.  Next differ pattern show in next post:

Hope you like this post

Plz share this!!! And have ou any query then write in comment.

If you declare private member in a class and want to call different class then you can you use setter getter concept.

Below the program mention using setter getter method.

Create multi.java class

create main class multi_mainclass.java

in this class calling the private member from the other class

Output:

package add_returnvalue;

import java.util.Scanner;

public class Add_returnvalue {

    int a=0,b=0;

                public void setA(int c)

                {

                                a=c;       

                }

                public int getA(){

                                return a;

                }

                public void setB(int d)

                {

                                b=d;      

                }

                public int getB(){

                                return b;

                }

                public int sum(){

                                int s=0;

                                s=a+b; 

                                return s;

    }

    public static void main(String[] args) {

        // TODO code application logic here

       Scanner obj= new Scanner(System.in);

                                Add_returnvalue d1= new Add_returnvalue();

                                System.out.println(" this program for Add of 2 no. plz enter a and b value:");

                                int a= obj.nextInt();

                                int b= obj.nextInt();

                                d1.setA(a);

                                d1.setB(b);

                                System.out.println("Value of A is :"+d1.getA());

                                System.out.println("Value of B is :"+d1.getB());

                                System.out.println("Add of 2 values is:"+d1.sum());       

    }

}

output:

If you declare private member in a class and want to call different class then you can you setter getter concept.

Below the program mention using setter getter method.

Create multi.java class

package add_returnvalue;

public class multi {

    private int a;

    private int b;

    public void setA(int a){

      this.a= a;

    }

    public int getA(){

        return a;

    }

    public void setB(int b){

        this.b= b;

    }

    public int getB(){

        return b;

    }  

}

create main class multi_mainclass.java

in this class calling the private member from the other class

package add_returnvalue;

public class multi_mainclass {

    public static void main(String[] args) {

    multi ml = new multi();

    ml.setA(20);

    ml.setB(10);

    System.out.println(ml.getA()*ml.getB());

}

}

Output:

let,s discuss on even or odd number, if you enter odd number like 1, 3,5, 7........... then show the result is "given no. is odd", or you enter number like- 2,4,6,8........... then show result is "given no. is even".

below the mention program to show given no is odd or even. i suggest you that you can program in netbeans.

// program to show given no. is odd or even in java
