arrays - 在数组上调用 toString - FindBugs

Question

我的代码出现以下 Findbugs 错误，

Invocation of toString on <<Package Path>>

 The code invokes toString on an array, which will generate a fairly useless
 result such as [C@16f0472. Consider using Arrays.toString to convert the
 array into a readable String that gives the contents of the array.
 See Programming Puzzlers, chapter 3, puzzle 12. 

代码:

logger.info("Adding information"+ Employee.getName()+ " "+
            employeeForm.getQuestionAndAnswers());

请让我知道是什么错误。

Answer 1

正如它所说，做

myArray.toString()

会产生像 java.lang.int[]@45345262 这样无用的东西

你想用

Arrays.toString(myArray);
