In this article, we would like to show you how to find a character index in string in Java.
Quick solution:
String text = "Dirask is awesome!";
int result = text.indexOf("D"); // 0
System.out.println(result);
Practical example
In this example, we use String.indexOf() method to find character index in the text string.
public class Example {
public static void main(String[] args) {
String text = "Dirask is awesome!";
int index1 = text.indexOf("D"); // 0
int index2 = text.indexOf("a"); // 3 (first occurrence)
int index3 = text.indexOf("Dirask"); // 0
int index4 = text.indexOf("is"); // 7
System.out.println(index1); // 0
System.out.println(index2); // 3 (first occurrence)
System.out.println(index3); // 0
System.out.println(index4); // 7
}
}
