Replace '*' with '^' with Java Regular Expressions

Java 8Object Oriented ProgrammingProgramming

To replace *' with '^' using Java Regular Expressions, we need to use the replaceAll() method. The replaceAll() method returns a String replacing all the character sequence matching the regular expression and String after replacement.

Declaration − The java.lang.String.replaceAll() method is declared as follows −

public String replaceAll(String regex, String replaced)  

Let us see a program to replace '*' with '^' using Java Regular Expressions −

Example

 Live Demo

public class Example {
   public static void main( String args[] ) {
      String str = new String("H*e*l*l*o");
      System.out.println( "Initial String : "+ str);
      // replacing '*' with '^'
      str = str.replaceAll( "\*", "^" );
      System.out.println( "The String after substitution : "+str );
   }
}

Output

Initial String : H*e*l*l*o
The String after substitution : H^e^l^l^o
