PassPrimitiveDatatypeTest.java
public class PassPrimitiveDatatypeTest
{

    public static void main(String[] args)
    {

        int x = 3;

        changeIt(x);

        System.out.println("x value inside main method : " + x);

    }

    /*
     * Passing Primitive Data Type Arguments :
     * 
     * Primitive arguments, such as an int or a double, are passed into methods
     * by value. This means that any changes to the values of the parameters
     * exist only within the scope of the method. When the method returns, the
     * parameters are gone and any changes to them are lost.
     */

    public static void changeIt(int x)
    {
        x = 50;
        System.out.println("x value inside changeIt method : " + x);
        return;
    }

}
Output
x value inside changeIt method : 50
x value inside main method : 3
