Replace/remove character in a String
To replace all occurences of a given character :
String myString = "Replace ' by * ";
String tmpString = myString.replace( '\'', '*' );
System.out.println( "Original = " + myString );
System.out.println( "Result = " + copyString );
To replace a character at a specified position :
public static String replaceCharAt(String s, int pos, char c) {
return s.substring(0,pos) + c + s.substring(pos+1);
}
To remove a character :
public static String removeChar(String s, char c) {
String r = "";
for (int i = 0; i < s.length(); i ++) {
if (s.charAt(i) != c) r += s.charAt(i);
}
return r;
}
To remove a character at a specified position:
public static String removeCharAt(String s, int pos) {
return s.substring(0,pos)+s.substring(pos+1);
}
