In this article, we would like to show you how to find text in string in Java.

Quick solution

String string = "Dirask is awesome!";
String text = "is";

// returns true if string contains text
boolean contains = string.contains(text);
System.out.println(contains);  // true

or

String string = "Dirask is awesome!";
String text = "is";

// returns index of the first occurrence of text in string
int index = string.indexOf(text);
System.out.println(index);  // 7

 

Practical examples

1. String.contains()

In this example, we use String.contains() method to check if the string contains text.

public class Example {

    public static void main(String[] args) {
        String string = "Dirask is awesome!";
        String text = "is";

        // returns true if string contains text 
        boolean contains = string.contains(text);
        System.out.println("contains = " + contains);  // true
    }
}

Output:

contains = true

2. String.indexOf()

In this example, we use String.indexOf() method to find the index of the first occurrence of text in the string.

public class Example {

    public static void main(String[] args) {
        String string = "Dirask is awesome!";
        String text = "is";

        // returns index of the first occurrence of text in string
        int index = string.indexOf(text);
        System.out.println("index = " + index);  // 7
    }
}

Output:

index = 7
