Primitive arguments for example, a double or an int, get passed by value into methods. This shows that changes to parameter values are present just in the method’s scope. When methods are returned it means that parameters have been gone & all alterations have been lost. For example:

Java Code:

public class PassPrimitiveByValue {

    public static void main(String[] args) {
           
        int x = 3;
           
        // invoke passMethod()
