String indexOf(int ch)

In this section, you will get the detailed explanation about the indexOf(int ch) method of String class.

In this section, you will get the detailed explanation about the indexOf(int ch) method of String class. We are going to use indexOf(int ch) method of String class in Java. The description of the code is given below for the usage of the method.

Description of the code:

Here, you will get to know about the indexOf(int ch) method through the following java program. In the program code given below, we have taken a String. To find the index of any character in a string we have applied indexOf() method and then we have passed a character from the string in that to find its index as shown in the output. You must be observing in the output that we have also taken the ASCII value of small "b" which is 98. Hence its also giving the same result.

NOTE: This method returns the index of the first occurrence of the given character within the string.

Here is the code of the program:


public class indexOfString {

  public static void main(String args[]) {

  String s = "That�was�the�breaking�News";

  System.out.println(s);

  System.out.println("indexOf(the) -> " + s.indexOf('b'));

  System.out.println("indexOf(the) -> " + s.indexOf(98));

  }

  }

Output of the program:

C:\unique>javac indexOfString.java

C:\unique>java indexOfString
That�was�the�breaking�News
indexOf(the) -> 13
indexOf(the) -> 13

C:\unique>
