//StringBuilder in Java represents a mutable sequence of characters.
// Example(1) Create StringBuilder without Arguments
StringBuilder name = new StringBuilder(); // Create a StringBuilder object
// Example(2) Create StringBuilder with Arguments
StringBuilder name = new StringBuilder("Computer System");
// Example(3) Change from String Object to StringBuilder Object
String name = "jack"; // String Object
StringBuilder name2 = new StringBuilder(name); // add String Object in StringBuilder Constructor
System.out.println(name2); // print StringBuilder Object
System.out.println(name2.toString); // print String Object
