Question

public class Overloading {

    static void printing() {
        System.out.println("Something being printed here");
    }

    static void printing(String name) {
        System.out.println("hello"+name);
    }

    public static void main(String[] args) {
        printing();
        printing(rizwana);
    }
}

我正在尝试检查方法重载。但这是我得到的错误。

error: cannot find symbol
            printing(rizwana);
symbol:   variable rizwana
location: class Overloading

Answer 1

rizwana是指您未在代码中创建的变量。如果要传递字符串，则应将其作为"rizwana"传递。

将方法称为：printing("rizwana");

Answer 2

printing（String name）方法将接受一个字符串参数。所以你应该使用打印（＆＃34; rizwana＆＃34;）而不是打印（rizwana）。你可以这个

class Overloading {

    static void printing() {
        System.out.println("Something being printed here");
    }

    static void printing(String name) {
        System.out.println("hello "+name);
    }

    public static void main(String[] args) {
        printing();
        printing("rizwana");
    }
}

方法重载 - 找不到符号
