从键盘输入

Question

我想从这个程序的用户那里获取值，即Name的值，roll，salary直接从用户那里获取

。

怎么做？

 public class MethodOverloadingPractice {
    public void display(String name){
        System.out.println("Name is "+name);
    }
    public void display(String name, int roll){
        System.out.println("Name is " + name + "Roll is " + roll);
    }
    public void display(String name, int roll, double salary){
        System.out.println("Name is " + name + "Roll is " + roll + "Salary is " + salary);
    }      
}
class MOP{
    public static void main(String[] args){
    MethodOverloadingPractice obj = new MethodOverloadingPractice();
    obj.display("Jannatin");
    obj.display("Jannatin", 101);
    obj.display("Jannatin", 101, 150);
    }
}

谁能帮忙？

您可以使用

Scanner 从命令行读取一行。

Scanner scanner = new Scanner(System.in);
scanner.useDelimiter(System.getProperty("line.separator"));
String name = scanner.next();
String roll = scanner.next();
String salary = scanner.next();
scanner.close();
