String indexOf(int ch, int fromIndex)
In this section, you will get the detailed explanation about the
indexOf(int ch, int fromIndex) method of
String class. We are going to use indexOf(int
ch, int fromIndex) 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, int fromIndex) 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(int ch, int
fromIndex); method and then we have passed the character from a string in that
with the index number to find its
index starting from the specified 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 with the index number. Hence its also giving the same result.
NOTE: This method returns the index of the first occurrence of the
given character, starting the search at the specified index within
the string.
Here is the code of the program:
public class IndexOfChar{
public static void main(String args[]) {
String s = "Honesty is the best Policy";
System.out.println(s);
System.out.println("indexOf(n, 1) -> " + s.indexOf('b', 1));
System.out.println("indexOf(n, 1) -> " + s.indexOf(98, 1));
}
}

Output of the program:
C:\unique>java IndexOfChar
Honesty is the best Policy
indexOf(n, 1) -> 15
indexOf(n, 1) -> 15
C:\unique> |
