Java StringBuilder class is used to create
  mutable (modifiable) string. The Java
  StringBuilder class is same as StringBuffer
  class except that it is non-synchronized.
    
StringBuilder()
    creates an empty string Builder with the initial capacity of 16.
StringBuilder(String str)
    creates a string Builder with the specified string.
StringBuilder(int length)

stringbuilder java

Comment

// Overuse of String concatenation can build large numbers of String objects
// a huge drain on performance and memory, hence code below is avoided
String firstName = "Chris";
String lastName = "Wells";
String fullName = firstName + " " + lastName;

// StringBuilder
// provides dynamic string manipulation without performance overhead of String class
StringBuilder nameBuffer = new StringBuilder("John");
nameBuffer.append(" ");
nameBuffer.append("Richard");
System.out.println(nameBuffer.toString());  //must convert to Strings before can be printed

Java StringBuilder

Comment

//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
