Setting Case Sensitivity in a Regular Expression

     

This section describes the method to set the patter is either case sensitive or not. Actually, by default the patter is in the case sensitive. Whenever it need to be set for the case insensitivity then you have to use the appropriate code followed in following program.

Code Description:

Pattern pattern = Pattern.compile(str, Pattern.CASE_INSENSITIVE):
Above code is used for setting the pattern case insensitive because the pattern is by default in case sensitive mode. By passing the Pattern.CASE_INSESITIVE field of the Pattern class is passed with the string, which has to be compiled for searching, as a parameter of the compile() method of the class.

Here is the code of the program:

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

public class RegExpSetForCaseSensitive{
  public static void main(String[] argsthrows IOException{
  BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
  System.out.print("Enter string: ");
  String string = in.readLine();
  System.out.print("Enter string for search: ");
  String str = in.readLine();
  Pattern pattern = Pattern.compile(str, Pattern.CASE_INSENSITIVE);
  Matcher matcher = pattern.matcher(string);
  String afterReplace = matcher.replaceAll("F");
  System.out.println(afterReplace);
  }
}
