Coding example: 41

As we have said earlier, Java has many built-in array methods that can help us manipulate an array according to our requirements.

Press + to interact
import java.util.Arrays;
/*
We can check if any array has a certain value
*/
public class ExampleFortyOne {
    public static void main(String[] args){
        //array declaration
        int[] myNumber = new int[3];
        //now we need to add elements
        myNumber[0] = 50;
        myNumber[1] = 60;
        myNumber[2] = 70;
        //etc
        int[] anotherNumber = {1, 2, 3};
        String[] nameColection = {"John", "Bob", "Mary"};
        System.out.println("Does array nameCollection contains this element? "
                + Arrays.asList(nameColection).contains(2));
        System.out.println("Does array nameCollection contains this element? "
                + Arrays.asList(nameColection).contains("John"));
    }
}

Code explanation

In the first case, we have passed a numerical value. As expected, the answer will be false. Because the array was of the String type, the next one is ...
