// All StringBuffer methods modify the value of the object.

// StringBuilder delete(int startIndex, int endIndexPlusOne)

System.out.println(sb.delete(3, 7));// 012789

System.out.println(sb1.insert(3, "ABCD"));// abcABCDdefgh

StringBuilder sb2 = new StringBuilder("abcdefgh");

// StringBuilder reverse()

System.out.println(sb2.reverse());// hgfedcba

// Similar functions exist in StringBuffer also

// All functions also return a reference to the object after modifying

// it.

// This allows a concept called method chaining.

System.out.println(sb3.reverse().delete(5, 6).insert(3, "---"));// hgf---edba
