Hi friend,

Code to solve the problem :

import java.util.regex.*;
import java.io.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ReadStringChar {
public static void main(String [] args) throws IOException{
try{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter First String");
String str= br.readLine();

System.out.println("Enter Character");
char ch = (char) System.in.read();
System.out.println("Ascii Value " + (int)ch);
int firstIndex= str.indexOf(ch);
System.out.println("firstIndex " + firstIndex);
String str1 = str.substring(firstIndex+1);
int secondIndex= firstIndex+str1.indexOf(ch)+1;
System.out.println("secondIndex " + secondIndex);
String strreplace = str.replace(ch, ' ');
System.out.println("strreplace " + strreplace);

}
catch(Exception e){
System.out.println("Out of range!");
}
}
}
