Example Analysis of reference Type and value Type in Java

This article shares with you the content of sample analysis of reference types and value types in Java. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Value type passes value, reference type passes reference

Demo:

Public class ReferDemo {

/ / public int Xerox 10

/ * *

* @ param args

* primitive type: number boolean type

* refer type: class array

, /

Public static void main (String [] args) {

/ / TODO Auto-generated method stub

/ / the value type passes the value, and the reference type passes the reference without changing the original value.

Int Xero1

Set (1)

System.out.println ("x:" + x)

String y = "y"

Set (y)

System.out.println ("y:" + y)

/ / the array is a reference type

String [] a=new String [1]

A [0] = "a [0]"

Set (a)

System.out.println (a [0]); / / out-print: "a [0]
