How to remove duplicate text in string.

[ramakrishnav]

Hi all,
i am new to Java...could you please help on this.
Scenario :
String Subject = RE:: This is test1 RE:: this is test2 RE:: this is test3 FW:: This is test1 FW:: this is test2 FW:: this is test3..

In Above Subject , RE & FW is repeating multiple times, i need to remove duplicate for both 'RE' & 'FW'..
so final o/p required as
String Subject = RE:: This is test1 this is test2 this is test3 FW:: This is test1 this is test2 this is test3.

how can we achive on this....
Thanks
Ram

    char[] characters = stringWithDuplicates.toCharArray();
    boolean[] found = new boolean[256];
    StringBuilder sb = new StringBuilder();
    System.out.println("String with duplicates : " + stringWithDuplicates);
    for (char c : characters) {
        if (!found[c]) {
            found[c] = true;
            sb.append(c);
        }
    }
    System.out.println("String after duplicates removed : " + sb.toString());
    }
