Question

所以，我需要得到这个输出：

循环1输出（低= 1，高= 10，增量= 1）

1 2 3 4 五 6 7 8 9 10

和

循环1输出（低= 2，高= 9，增量= 3）

2 五 8

但我只是第二个。这是我的代码：

public void loop1(int lower, int upper, int increment)
{   

    System.out.println("Loop 1 Output (lower= " + lower+ "," +
            " upper= " + upper+ "," + " increment= " + increment+ ")"); 
    for(int i = lower; i <= upper; i += increment)
    {
        System.out.println(i);
    }       
    System.out.println("-----------------------------");
  }

你能帮帮我吗？

更新：这是我的代码：

    public void loop1(int lb, int ub, int incr)
{   

    System.out.println("Loop 1 Output (lb = " + lb + "," +
            " ub = " + ub + "," + " incr = " + incr + ")"); 
    for(int i = lb; i <= ub; i += incr)
    {
        System.out.println(i);
    }       
    System.out.println("-----------------------------");
  }


public void loop2(int lb, int ub, int incr)
{

    System.out.println("Loop 2 Output (lb = " + lb + "," +
            " ub = " + ub + "," + " incr = " + incr + ")");
    int n = lb;
    while(n <= ub)
    {
        System.out.println(n);
        n += incr;
    }
    System.out.println("-----------------------------");
}

这是我的输入类：

public class Driver

public static void main (String [] args)

    Loop lp = new Loop();

    lp.loop1(1, 10, 1); 
    lp.loop2(1, 10, 1);

    lp.loop1(2, 9, 3);
    lp.loop2(2, 9, 3);

谢谢！

Answer 1

也许您只调用一次方法，尝试调用：

loop1(1,10,1);
loop1(2,9,3);

我在这里测试过并且工作过：

使用loop1和1, 10, 1

呼叫2, 9, 3

public static void main(String[] args) {
    loop1(1, 10, 1);
    loop1(2, 9, 3);
}

然后我相信您需要static方法，并且可以使用printf()格式化输出，例如

public static void loop1(int lower, int upper, int increment) {
    System.out.printf("Loop 1 Output (lower=%d, upper=%d, increment=%d)%n",
            lower, upper, increment);
    System.out.print(lower);
    for (int i = lower + increment; i <= upper; i += increment) {
        System.out.printf(" %d", i);
    }
    System.out.printf("%n-----------------------------%n");
}

无论如何，上述内容对我有用。

在同一个循环中有两个输出的循环增量？
