import java.lang.reflect.Method;

public class Example {

	public static void main(String[] args) {
		int a = 30;
		int b = 45;
		System.out.println("Before swapping, a = " + a + " and b = " + b);

		// Invoke the swap method
		swapFunction(a, b);
		System.out.println("\n**Now, Before and After swapping values will be same here**:");
		System.out.println("After swapping, a = " + a + " and b is " + b);
	}

	private static void swapFunction(int a, int b) {
		// TODO Auto-generated method stub

		System.out.println("Before swapping(Inside), a = " + a + " b = " + b);
		// Swap n1 with n2
		int c = a;
		a = b;
		b = c;
		System.out.println("After swapping(Inside), a = " + a + " b = " + b);
