Question

我在缩短代码方面遇到了问题。样本输出：你会输入多少个整数？ 4 输入4个整数，每行一个： 2 1 1 2 总和是6。数字是： 2是总和的33.33％。 1是总和的16.67％。 1是总和的16.67％。 2这是总和的33.33％。

示例输出应为此。我已经完成并执行任务，但我的代码很长。

Answer 1

我认为这可能会对你有所帮助，但我认为这是你的功课，所以最好先理解代码，然后自己尝试。

@Test
public void myTest()
{
    // Prepare the input parameters:
    ...

    // Perform the test:
    try
    {
       int result=countFieldEventPoints(row, centimeters);
       // Check the results:
       assert...
    }
    catch (SomeException e)
    {
        fail(messsageInCaseOfFail);
    }
}

需要帮助缩短我在java中的代码（netbeans）
