The explanation was precise and useful

[monishamoni.]

Simply stated, objects of type String are read only and immutable. The StringBuffer class is used to represent characters that can be modified. The significant performance difference between these two classes is that StringBuffer is faster than String when performing simple concatenations.

Well, the most important difference between String and StringBuffer/StringBuilder in java is that String object is immutable objects are mutable. By immutable, we mean that the value stored in theString object cannot be changed.Feb 15, 2008

A thread-safe, mutable sequence of characters. A string buffer is like a String, but can be modified. ... Java provides the StringBuffer and String classes, and the String class is used to manipulate character strings that cannot be changed. Simply stated, objects of type String are read only and immutable.Mar 13, 2010

String class overrides the equals() method of Object class. So you can compare the contents of two strings by equals() method.

StringBuffer class doesn't override the equals() method of Object class.

[hemamalinig]

Java String class provides a lot of methods to perform operations on string such as compare(), concat(), equals(), split(), length(), replace(), compareTo(), intern(), substring() etc.

The java.lang.String class implements Serializable, Comparable and CharSequence interfaces.

String is immutable whereas StringBuffer and StringBuider are mutable classes. StringBuffer is thread safe and synchronized whereas StringBuilder is not, thats why StringBuilder is more faster than StringBuffer. String concat + operator internally uses StringBuffer or StringBuilder class.

[samuelsam]

As you will find that there are minor differences between the above mentioned classes. String is immutable ( once created can not be changed )object . The object created as a String is stored in the Constant String Pool . Every immutable object in Java is thread safe, that implies String is also thread safe .

[deenasteyn]

StringBuffer and StringBuilder have the same methods with one differenceand that's of synchronized( which means it is thread safe and hence you can use it when you implement threads for your methods) whereasStringBuilder is not synchronized( which implies it isn't thread safe).
