Question

Let’s say I got this array:

String[][]array = new String[5][5];

array[2][2] = desperate;

Would it be possible to find whether

String s = “desperate”; – equals any array element without using a for loop, and without having to manually enter the row column combination of the array assigned the value “desperate”?

Answer 1

Use enhanced-for loop: –

String [][] array = new String[2][2];
array[1][1] = "desperate";
array[0][1] = "despee";
array[1][0] = "despete";
array[0][0] = "dete";

for (String[] innerArr: array) {
    for (String value: innerArr) {
         if (value.equals("desperate")) {
             System.out.println(value + " == desperate");
         }
    }
}

Output: – desperate == desperate

A better way that I would suggest is to use ArrayList<String> to store your items.. Then you can just call contains() method to check whether the list contains that element..

List<String> listString = new ArrayList<String>(); 
listString.add("desperate");
listString.add("despe");

if (listString.contains("desperate")) {
     System.out.println("True");
}

Output: – True
