How to find the Index of Last Occurrence of Substring in Java ?

Answer

To find the index of the last occurrence of a substring in Java, you can use the lastIndexOf method of the String class.

✐ Examples

1 Find Index of Last Occurrence in String

In this example,

We create a variable named str with a string value.
We use the lastIndexOf method of str to find the index of the last occurrence of a specific substring within str.
The lastIndexOf method returns the index of the last occurrence of the substring in the string.
Finally, we print the index.

Java Program

// Find Index of Last Occurrence in String
public class Main {
    public static void main(String[] args) {
        String str = "Hello World, Hello Java";
        int lastIndex = str.lastIndexOf("Hello");
        System.out.println("Last index of substring is: " + lastIndex);
    }
}

Output

Last index of substring is: 13

2 Find Index of Last Occurrence in Another String

In this example,

We create two variables named str1 and str2 with different values.
We use the lastIndexOf method of str1 to find the index of the last occurrence of str2 within str1.
The lastIndexOf method returns the index of the last occurrence of str2 in str1.
Finally, we print the index.

Java Program

// Find Index of Last Occurrence in Another String
public class Main {
    public static void main(String[] args) {
        String str1 = "apple banana cherry banana";
        String str2 = "banana";
        int lastIndex = str1.lastIndexOf(str2);
        System.out.println("Last index of substring is: " + lastIndex);
    }
}

Output

Last index of substring is: 20
