public class Test5{
public static void main(String[] args){
String s=new String("World");
char[] c={'a','s','d'};
change(s,c);
System.out.print(s+" and ");
for(int i=0;i<c.length;++i){
System.out.print(c[i]);
}
}
public static void change(String s,char[] c){
s="chaged";
c[0]='c';
c[1]='v';
c[2]='v';
}
}

结果是:World and cvv

数组是怎样传递参数的?成员变量和方法参数变量有什么不同??

还是好好把书看看吧
很基础的知识啊
public static void change(String s,char[] c){
s="chaged";
c[0]='c';
c[1]='v';
c[2]='v';
}
中的s是局部变量
