public class Container {
    private int value;
    public Container(int value){
        this.value=value;
    }
    public int getValue(){
        return this.value;
    }
    public int sum(Container c){
        return this.value+c.getValue();
    }
    public void main(){
        Container c1=new Container(1);
        Container c2=new Container(2);
        System.out.println("sum: " + c1.getValue()+c2.getValue());
        System.out.println("sum: " + c1.sum(c2));
    }
}

当我运行此代码时，我得到以下结果：

public class Container {
    private int value;
    public Container(int value){
        this.value=value;
    }
    public int getValue(){
        return this.value;
    }
    public int sum(Container c){
        return this.value+c.getValue();
    }
    public void main(){
        Container c1=new Container(1);
        Container c2=new Container(2);
        System.out.println("sum: …
