With this example we are going to demonstrate how to pass an object to a method. In short, we have created a class and a method to pass the object of the class:
- We have created a class,
Characterwith a char field. - We have created another class,
PassObject, that has a static method,void setCh(Character y). The method gets aCharacterobject and changes its char field to'z'. - We create a new instance of
Characterclass and set its char field to'a'. - Then we use the
setCh(Character y)method ofPassObjectclass to change again the field ofCharacterobject. - In both ways the field of Character object is changed.
Let’s take a look at the code snippet that follows:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | package com.javacodegeeks.snippets.core;class Character { char ch;}public class PassObject { static void setCh(Character y) { y.ch = 'z'; } public static void main(String[] args) { Character x = new Character(); x.ch = 'a'; System.out.println("1: x.ch: " + x.ch); setCh(x); System.out.println("2: x.ch: " + x.ch); }} |
Output:
1: x.ch: a
2: x.ch: z
