The weight of something is another way of describing the amount of force exerted on （) by gravity.

public class Something {

public static void main(String[] args) {

Something s = new Something();

System.out.println("s.doSomething() returns " + doSomething());

}

public String doSomething() {

return "Do something ...";

}

}

看上去很完美。

public class Something {

public static void main(String[] args) {

Something s = new Something();

System.out.println("s.doSomething() returns " + doSomething());

}

public String doSomething() {

return "Do something ...";

}

}

看上去很完美。
