我是Java新手，我现在正在学习。我想创建一个小程序，可以总结我在程序中显示的所有数字。我的程序的主要思想要求我提供许多数字。这是循环：

for (int k = 1; k <= 6 ; k++){
    System.out.println("Type " + k +". number");
    f = userInput.nextInt();
}

我想知道我的程序如何总结我所有的数字？

您需要声明一个变量来保存总和：

int f, sum = 0;
for (int k = 1; k <= 6 ; k++){

    System.out.println("Type " + k +". number");
    f = userInput.nextInt();
    sum += f;
}

Try this

    int answer = 0;
    for (int k = 1; k <= 6 ; k++){

        System.out.println("Type " + k +". number");
        f = userInput.nextInt();
        answer += f; 

    }
    System.out.println(answer);

// assuming userInput is a Scanner

int sum = 0;

int f;

for (int k = 1; k <= 6 ; k++){

    System.out.println("Type " + k +". number");
    f = userInput.nextInt();

    sum += f;

}

// sum now holds the sum of all numbers

Assuming you did create a scanner object before this segment of code you can simply have a sum variable that hold the sum of your inputs.

       int sum =0;
       for (int k = 1; k <= 6 ; k++){

            System.out.println("Type " + k +". number");
            f = userInput.nextInt();
            sum += f;    
        }

for (int k = 1; k <= 6; k++) {

    f = userInput.nextInt();

    sum = sum + f;
