The output of the preceding program is as follows:

                     BlueJ: Terminal Window - Java
                 Options

                The Extracted string is: New


              The replace(char chartoreplace, char chartoinsert) Function
              This function replaces all the characters mentioned in ‘chartoreplace’ with the characters given in ‘chartoinsert’  and
              creates a new String. The syntax is:

                  String <variable> = String_datatype_Variable.replace(char chartoreplace, char chartoinsert);
              Let us see the below example:

                               Write a program to replace all occurrences of the character ‘i’ with ‘a’ in the string “Rama is
                Program 12
                               going to play cricket” and display the result.
                1       class substring

                2       {

                3       public static void main(String[] args)
                4       {
                5       String str= "Rama is going to play cricket";

                6       String replacechar= str.replace(‘i’, ‘a’);
                7       System.out.println("The replaced string is: " + replacechar);

                8       }
                9       }

              The output of the preceding program is as follows:

                     BlueJ: Terminal Window - Java
                 Options

                The replaced string is: Rama as goang to play cracket


              The replace(String stringtoreplace, String stringtoinsert) Function
              This function replaces all the sequence of characters given in ‘stringtoreplace’ with the sequence of characters given
              in ‘stringtoinsert’  and creates a new String. It replaces all the sets having the same sequence. The syntax is:

                  String <variable> = String_datatype_Variable.replace(String stringtoreplace, String
                  stringtoinsert);
              Let us see the below example:

                               Write a program to replace all occurrences of the word “Morning” with “Evening” in the
                Program 13
                               string and display the result.
                1       class stringReplace

                2       {
                3       public static void main(String[] args)

                4       {
