java的打印与Arrays.toString阵列（）错误 [英] java printing an array with Arrays.toString() error

问题描述

所以我尝试打印的int数组在我的计划，并按照这些指令的最简单的方法打印在Java中数组

写了下面的code：

  INT []总访问量= //方法返回int数组
    的System.out.println（Arrays.toString（总计））;
 

但它不会编译说

  

类对象toString方法不能被应用到给定的类型。
  要求：无参数
  发现：INT []
  原因：实际的和正式的参数列表的长度不同

为什么会这样？难道我没有通过我的数组作为参数传递给的toString？如果没有，我怎么使用的toString？

感谢您！

解决方案

  

类Object toString方法不能被应用到给定的类型。要求：未发现参数：INT []的原因：实际的和正式的参数列表的长度不同

可能是你有一个名为变量阵列，这就是为什么编译器抱怨你试图调用思维 Object.toString（） ，它不带任何参数。

尝试

 的System.out.println（java.util.Arrays.toString（总计））;
 

So I was trying to print an array of ints in my program, and following these instructions Simplest way to print an array in Java

wrote the following code:

    int[] totals = //method that returns int array
    System.out.println(Arrays.toString(totals));

But it wont compile saying that

"method toString in class Object cannot be applied to given types. required: no arguments found: int[] reason: actual and formal argument list differ in length"

Why does it do that? Do I not pass my array as an argument to toString? If not, how do I use toString?

Thank you!

解决方案

method toString in class Object cannot be applied to given types. required: no arguments found: int[] reason: actual and formal argument list differ in length

May be you have a variable named Arrays, that's why the compiler is complaining thinking that you are trying to invoke the Object.toString(), which doesn't take any argument.

Try

 System.out.println(java.util.Arrays.toString(totals));
