您好如何使用eclipse进行用户输入。就像命令提示符一样，我们

C：/ java javaApp（这里的参数）。如何使eclipse从用户那里获取输入。？

Answer 1

运行 - ＆gt;运行配置 - ＆gt;参数（它是右边的第二个标签） - ＆gt;程序参数

Answer 2

在程序中添加此行以接受来自控制台的用户输入：

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

然后在要从Runtime接受输入的任何变量旁边添加in.readLine（）。可以说，您希望将count变量初始化为值1，然后，它应该写为

int count = in.readLine(); 运行程序

后，应在控制台中输入值1

Answer 3

以下是在Eclips中获取用户输入的一种方法。

import java.util.Scanner; // enter the before the start of any class 
// declare the class here 
// this is an example of how to use the Scanner in a method
Public static void Username();{
Scanner Input = new scanner (System.in);
String username// declaring the username variable 
Scanner un = new Scanner(System.in); //  un is just a random variable you can choose any other variable name if you want
System.out.println("Enter Your Username");
username = un.next(); 
System.out.println("The username you entered is : " + username);}

但是如果你想在这里采用整数或双数作为输入，你将如何做。我将给出一个int输入的例子，你只需要用double替换int。

import java.util.Scanner; 
// Declare the class here
// this is an example of how to use the Scanner in a method for an integer input by user
Public static void booksRead();{
Scanner Input = new scanner (System.in);
int books // declaring the books variable 
Scanner br = new Scanner(System.in); //  br is just a random variable you can choose any other variable name if you want
System.out.println("Enter how many books have you read: ");
books = br.next(); 
System.out.println("The number of books you have read is : " + books);}

Answer 4

这将打印用户输入的数字：

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner reader = new Scanner(System.in);  // Reading from System.in
    System.out.println("Enter a number: ");
    int n = reader.nextInt(); // Scans the next token of the input as an int.
    //once finished
    System.out.println(n);
    reader.close(); 
}
