如何修复此错误：对象类型中的 toString() 方法不适用于参数？

Question

I created an array of numbers. Now I want that array to be displayed in the output so I used System.out.println .

But if we do that, the array won't be shown so we have to convert the array into a string just before we display it. To do that, we could use Arrays.toString() function.

It's showing the following error:

The method toString() in the type Object is not applicable for the arguments?

Below is the code I want to execute:

public class Arrays {
  public static void main (String[] args) {
    int[] array1 = new int[] {1, 2, 3};
    System.out.println((Arrays.toString(array1);
  }
}

Answer 1

Few things:

• Arrays.toString() accepts an array as a parameter. Pass array1 to the method
• Your class name Arrays is conflicting with the java.util.Arrays class. Either rename the class or use a direct path (demonstrated below).
• You are missing some ending brackets

Try this:

public class Arrays {
  public static void main (String[] args) {
    int[] array1 = new int[] {1, 2, 3};
    System.out.println(java.util.Arrays.toString(array1));
  }
}

Which prints :

[1, 2, 3]
