String instances are immutable. As a result, methods like replaceAll() do not modify the original string but instead return a modified copy of the string. So replace foo.replaceAll(...) with foo = foo.replaceAll(...).

U can also use a if statement and traverse the whole string . If a comma(,) is found replace it with a space(" ").

you can use substring method of String class. or You can use deleteCharAt() method of StringBuilder or StringBuffer class
StringBuffer sb=new StringBuffer(your_string);sb.deleteCharAt(sb.length()-1);
