如何使Eclipse中有误申报异常时，不抓？

问题描述

如何让Eclipse来报告错误申报异常时，不抓？结果
例如，如果我声明的方法

 公众诠释的someMethod（INT A，INT B）抛出：IllegalArgumentException  -  {
    ...
}
 

，然后用它的另一种方法，如

 公众诠释anotherMethod（）{
    ...
    返回的someMethod（A，B）;
}
 

我想编译器以anotherMethod报告错误，直到我将捕获或抛出：IllegalArgumentException声明其他方法

 公众诠释anotherMethod（）抛出：IllegalArgumentException  -  {}
 

解决方案

由于您在anotherMethod一个未捕获IOException异常（）的Eclipse实际上应报告错误：

 未处理的异常类型为IOException
 

只有一个未经检查的异常（例如一个RuntimeException）会导致你所描述的行为，而是一个IOException异常是经过检查的异常。

也许你已经在Eclipse中关闭错误报告，但我怀疑如此。您可以在preferences /常规/编辑/文本编辑器/注释/错误检查。确保所有复选框被选中。

的注：我的答案是指原来的问题问编辑之前，里面提到一个IOException，而不是一个IllegalArgumentException 的

How to make Eclipse to report error when declared exception is not caught?
For example, if I declare method as

public int someMethod(int a, int b) throws IllegalArgumentException {
    ...
}

And then use it in another method like

public int anotherMethod() {
    ...
    return someMethod(a, b);
}

I want compiler to report error in anotherMethod, until I will catch IllegalArgumentException or declare another method as

public int anotherMethod() throws IllegalArgumentException {}

解决方案

Eclipse should actually report an error because you have an uncaught IOException in anotherMethod():

Unhandled exception type IOException

Only an unchecked exception (e.g. a RuntimeException) would cause the behaviour you are describing, but an IOException is a checked exception.

Maybe you have turned off error reporting in eclipse, but I doubt so. You can check this in Preferences / General / Editors / Text Editors / Annotations / Errors. make sure all checkboxes are checked.

Note: My answer refers to the original question asked before it was edited, which mentioned an IOException instead of an IllegalArgumentException.
