我正在做学校作业,一切看起来都不错,我甚至休息一下然后回来但是代码应该在执行时显示
Please enter an integer >> 14
Please enter another integer >> 11
14 + 11 is 25
14 - 11 is 3
The average of 14 and 11 is 12
但是当我执行它时,它只会读取
Please enter an integer >> 14
我正在使用Eclipse和它的统计数据我的扫描仪输入命令有问题,但我不确定它是什么,谢谢你的帮助。

您的print语句不应包含该号码。它应该只读" System.out.print("Please enter a double >> ")
"。这是第一个问题。此外,您的提示读取"请输入双",但您正在读取整数。将该行更改为input.nextDouble()
。否则,它会按预期完全运行。它打印"请输入双>> ",我键入一个数字,它打印下一行,我输入另一个数字,然后输出信息。请查看java.util.Scanner

它按预期运行
Please enter a double >> 1414
Please enter another double >> 11 11
14 + 11 is 25
14 - 11 is 3
The average of 14 and 11 is 12
该号码在提示中出现两次。我建议你把代码更改为
System.out.print("Please enter a double >> ");
firstNumber = input.nextInt();
System.out.print("Please enter another double >> ");
secondNumber = input.nextInt();

您是否正在为您的计划提供继续所需的输入?正如彼得斯回答的那样,你已经打印了14并且还没有输入它。我知道这有点傻,但这可能就是你的节目悬而未决的原因。
