Java笔试题-string、char[]

public class Demo {
    String str = new String("good");

    char[] chs = new char[] { 'a', 'b', 'c' };

    public void change(String str, char[] chs) {
        // str = "test ok";
        str = new String("good");
        chs[0] = 'g';
        System.out.println(this.str.intern() == str.intern());
        System.out.println(this.str == str);
        System.out.println(this.chs == chs);

    }

    public static void main(String[] args) {
        Demo demo = new Demo();
        demo.change(demo.str, demo.chs);
        System.out.println(demo.str + "---");
        System.out.println(demo.chs);
    }
