Programs over different functions provided by String Class:
package quipoin.javaeasyprograms;
public class BasicStringFunctions {
public static void main(String[] args) {
String s="Hello this is QuipoIn";
// Gives the length of String

// Remove spaces between the words
System.out.println(s.stripTrailing());
// Replace spaces with underscore
System.out.println(s.replace(" ","_"));
// Join or concatenate two Strings
System.out.println(s.concat(".com"));
// Check whether given char sequence is present or not
System.out.println(s.contains("this"));
// Check whether the given String is empty or not
System.out.println(s.isEmpty());
// Create a substring of given String
System.out.println(s.substring(6));
