java类静态属性测试

java中的类静态属性在多个实例化对象中是共用的。

public class Comm {public static  String test = "123";public String getTest() {return test;}public void setTest(String test) {Comm.test = test;}}/**************test*************/Comm c =new Comm();Comm d =new Comm();System.out.println("test = "+c.getTest());System.out.println("test = "+d.getTest());Comm.test = "zzzzzzzzzzzz";System.out.println("test = "+c.getTest());System.out.println("test = "+d.getTest());d.setTest("cccccccccccccc");System.out.println("test = "+c.getTest());System.out.println("test = "+d.getTest());

结果：

test = 123
test = 123
test = zzzzzzzzzzzz
test = zzzzzzzzzzzz
test = cccccccccccccc
test = cccccccccccccc
