Question

public class lsjdflsjdf {
public static void main(String[] args) {
    Scanner s = new Scanner(System.in);
    int input, sum = 0, count = 0;
    System.out.print("Enter a positive integer number: ");
    input = s.nextInt();

    while (input != -1) {
        count++;
        sum += input;
        System.out.print("Enter a positive integer number: ");
        input = s.nextInt();
    }

    System.out.println("Entered Number:\t" + count);
    System.out.println("The Sum:\t\t" + sum);
}

}

如何获取所有输入，以便它们可以显示在最后的“输入数字”println语句中，以便显示如下：

   Entered Number:  10, 2, 13, 50, 100
   The Sum:         175

   Entered Number:  1, 2, 3, 4, 5, 6, 7, 8, 9, 10
   The Sum:         48

   Entered Number:  1, 1, 1, 1, 100
   The Sum:         104

   Entered Number:  0, 0, 0, 0, 0, 100
   The Sum:         100

删除计数并将其替换为fcm/gradle/wrapper/gradle-wrapper.properties to gradle-2.10-all.zip，它将报告已输入的数字。一个简单的解决方案是将新输入与while循环中的现有输出连接起来。

例如：

String

您还可以使用StringBuilder来构建输出public static void main(String[] args) { Scanner s = new Scanner(System.in); int input, sum = 0; System.out.print("Enter a positive integer number: "); input = s.nextInt(); String outputString = ""; //our result string while (input != -1) { outputString += input + " "; //adding to the output string sum += input; System.out.print("Enter a positive integer number: "); input = s.nextInt(); } System.out.println("Entered Number:\t" + outputString); System.out.println("The Sum:\t\t" + sum); }。

如何在while循环中获取所有用户输入并将它们放入print语句中
