How are parameters passed in Java?
See this for detailed description.
In Java, parameters are always passed by value. For example, following program prints i = 10, j = 20.
// Test.java class Test { // swap() doesn't swap i and j public static void swap(Integer i, Integer j) { Integer temp = new Integer(i); i = j; j = temp; } public static void main(String[] args) { Integer i = new Integer( 10 ); Integer j = new Integer( 20 ); swap(i, j); System.out.println( "i = " + i + ", j = " + j); } } |
