Hello friends! Welcome to my blog
Here we discuss how to swap two numbers in java language and there are two methods to swap two numbers in java
Enter the two number
4
6
Number before Swap:
a=4
b=6
Number After Swap:
a=6
b=4
Enter the two number
4
7
Number Before Swap:
a=4
b=7
Number After Swap:
a=7
b=4
I make this programming and hope you are like the post if are you like the post you can please comment and Share the post to reach more people.

Here we discuss how to swap two numbers in java language and there are two methods to swap two numbers in java
1. swap two numbers without using third variable in java.
2. swap two numbers with using third variable in java.
See Example below
Swap two numbers without temp in java
import java.util.Scanner;
public class swap_without {
public static void main(String[] args) {
int a ,b;
Scanner in = new Scanner(System.in);
System.out.println("Enter the two number");
a=in.nextInt();
b=in.nextInt();
System.out.println("Number before Swap:\n a="+a+"\n b="+b);
a=a+b;
b=a-b;
a=a-b;
System.out.println("Number After Swap:\n a="+a+"\n b="+b);
}
}
public class swap_without {
public static void main(String[] args) {
int a ,b;
Scanner in = new Scanner(System.in);
System.out.println("Enter the two number");
a=in.nextInt();
b=in.nextInt();
System.out.println("Number before Swap:\n a="+a+"\n b="+b);
a=a+b;
b=a-b;
a=a-b;
System.out.println("Number After Swap:\n a="+a+"\n b="+b);
}
}
Enter the two number
4
6
Number before Swap:
a=4
b=6
Number After Swap:
a=6
b=4
Swap two numbers in java
import java.util.Scanner;
public class swap {
public static void main(String[] args) {
int a ,b;
Scanner in = new Scanner(System.in);
System.out.println("Enter the two number");
a=in.nextInt();
b=in.nextInt();
System.out.println("Number Before Swap:\n a="+a+"\n b="+b);
int temp=a;
a=b;
b=temp;
System.out.println("Number After Swap:\n a="+a+"\n b="+b);
}
}
public class swap {
public static void main(String[] args) {
int a ,b;
Scanner in = new Scanner(System.in);
System.out.println("Enter the two number");
a=in.nextInt();
b=in.nextInt();
System.out.println("Number Before Swap:\n a="+a+"\n b="+b);
int temp=a;
a=b;
b=temp;
System.out.println("Number After Swap:\n a="+a+"\n b="+b);
}
}
Enter the two number
4
7
Number Before Swap:
a=4
b=7
Number After Swap:
a=7
b=4
