來自鍵盤的輸入

Question

我想從用戶那裏獲取該程序的值，即直接來自用戶的值爲Name,roll,salary。

如何做到這一點？

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); 
    } 
} 

任何人都可以幫忙嗎？

您可以使用Scanner從命令行讀取一行。

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();
