英文:
Accessing a private String through a reference
问题
我需要访问私有字符串中的消息，我认为可以通过使用引用轻松完成，但这会强制我插入一条新消息，这将替换以前的消息。
class Test {
private String s = "This is string s";
String methodS(String a) {
a = s;
return s;
}
}
class name {
public static void main(String args[]) {
Test elen = new Test();
System.out.println(elen.methodS("This is string s in another class."));
}
}
英文:
I need to access the message in a private String, I though it could be done easily by using a reference, however it then forces me to insert a new message that will replace the backwards one.
class Test {
private String s = "This is string s";
String methodS(String a) {
a = s;
return s;
}
}
class name {
public static void main(String args[]) {
Test elen = new Test();
System.out.println(elen.methodS("This is string s in another class."));
}
}

你可以在你的类内部编写一个获取私有字段的getter方法。
String getS(String a) {
return s;
}
英文:
You can write a getter method inside your class to get the private field.
String getS(String a) {
return s;
}
