String str
= "good";
char[] ch
= {'a', 'b', 'c'};
public static void main(String
[] args
) {
Temp ex
= new Temp();
ex
.change(ex
.str
, ex
.ch
);
System
.out
.print(ex
.str
+ "and");
System
.out
.print(ex
.ch
);
}
public void change(String str
, char[] ch
) {
str
= "test ok";
ch
[0] = 'g';
}
此时画个图分析一下：思路比较清晰（String 数组都是对象 也就是引用类型变量）
