⊙final定义的常量不能修改
package cn.sg.final01;
public class Main {
public static void main(String[] args) {
//定义一个变量
int a = 100;
String b = "100";
a = 200;
b+="gnr" ;
System.out.println(a);
System.out.println(b);
//定义一个常量
final int MAX = 100;
//MAX = 200; 出错：final修饰的常量不能修改
//MAX = 200;
final String GAME = "WOW";
//final修饰的常量不能修改
//GAME = "WOW";
}
}
运行结果：
