In this post, we will learn to find the first occurrence of a character in string using java
As like in above image we are going to take String “BeginnersBug” for our example.
This array starts from 0 index to 11.
In this example, we are going to find the first occurrence of character ‘e’. which is 1
Note: that indexOf is case sensitive. It will return -1 if the character is not found
Syntax
int indexOf = s.indexOf('e');Example
public class FirstOccurance {
public static void main(String[] args) {
try {
String s = "BeginnersBug";
int indexOf = s.indexOf('e');
System.out.println("The first occurance of e is " + indexOf);
} catch (Exception e) {
e.printStackTrace();
}
}
}Example
The first occurance of e is 1Github
