I want to replace "^" with blank but the first "^" before any word should remain as it is for eg in the above string i should get output as : "^Test^Test^Test"

Answer 3

Sorry for late answer.
This is a example how you could do it.

In your main:
String a1 = "^Test^Test^^Test^^^^^^Test";
a1 = remDup(a1.toCharArray());
System.out.println(a1);

And use this method:
static String remDup(char[] ch) {

int c = 0;
char p = ' ';

for (int i = 0; i < ch.length; i++)
if (p != ch[i]) {
ch[c++] = ch[i];
p = ch[i];
}

return new String(ch).substring(0, c);
}

This will remove duplicate characters
