java - Java - (String[] args) 数组传递给类主方法

Question

    System.out.println(args[0] == "x");
    System.out.println(args[0].equals("x"));

    String[] name = {"x"};
    System.out.println(name[0] == "x");
    System.out.println(name[0].equals("x"));

    String[] hello = new String[1];
    hello[0] = "x";
    System.out.println(hello[0] == "x");
    System.out.println(hello[0].equals("x"));

结果是

false
true
true
true
true
true

当我调用“java classname x”时，为什么第一个测试结果为“假”？
