在数组上调用indexOf时无法解析为类型

Question

The nums.indexOf keeps getting an error that states

indexOf cannot be resolved or is not a field.

Am I supposed to import something? I have already imported java.util.* ;

public static int search(int[] nums)
{
    Scanner keyboard = new Scanner(System.in);
    System.out.println("What value do you want?");
    int value = keyboard.nextInt();
    for(int i = 0; i < nums.length; i++)
    {
        if(nums.indexOf[i] == value)
            return value;
        else 
            return "Value is not in the list";
    }
}

Answer 1

An array does not have a method 'indexOf'.

Use it like this:

if(nums[i] == value)

Sidenote: use braces ( {} ) around your if-else statements. It's not mandatory but it is definitely advised to avoid problems in the future.

Answer 2

Arrays don't have indexOf() method. Also instead of looping on the array you can use

Arrays.asList(nums).contains(i);
