Hey Farheen, StringBuffer vs StringBuilder. StringBuffer is the thread safe utility class to perform several operations on Strings. It contains append() and insert() methods that are widely used to perform operation on Strings in a multi-thread environment. Hope this helps!

Hey Vignesh, "String does not allow appending. Each method you invoke on a String creates a new object and returns it. This is because String is immutable - it cannot change its internal state. On the other hand StringBuilder is mutable. When you call append(..) it alters the internal char array, rather than creating a new string object. Thus it is more efficient to have" Hope this helps!
In the following example I am getting the output as "References are unequal' but i am expecting the output as "References are equal" since S3 and S4 are created using string class. Can anyone explain me this String S1="Mary"; String S2="John"; String S3=S1+S2; String S4=S1+S2; if (S3==S4) SOP("References are equal"); else SOP("References are unequal");

Why there is two way to create String And in which case we can go for String literal and in which case we can go for using new operator to create String
Hey Deepak, "Hi, When you create a String using literal, it is created in the string pool. Now if you try to create another object with the same value, JVM will give you the reference of that string and no new String object will be created. But when you create a String using new() keyword JVM is forced to create a new string reference, even if the String is already present in the reference pool. Hope this clears your doubt. Cheers!"

Hey Sushma, Java String indexOf() The java string indexOf() method returns index of given character value or substring. If it is not found, it returns -1. The index counter starts from zero. hope this is helpful! Cheers!
toString() method in Java is used to represent any object as a string. This method returns a string representation of an object. To print any object, Java internally invokes the toString method on the object.

Since stringbuilder is not threadsafe. then what is the need of stringbuilder ?. we can directly work with stringbuffer right.
Hey Vignesh, "String does not allow appending. Each method you invoke on a String creates a new object and returns it. This is because String is immutable - it cannot change its internal state.
On the other hand StringBuilder is mutable. When you call append(..) it alters the internal char array, rather than creating a new string object.
Thus it is more efficient to have"
Hope this helps!
Stringbuffer is for single thread environment but stringbuilder works with multi threaded environment
Although StringBuilder is not thread safe, it is faster than StringBuffer so when performance is a concern over thread safety SBuilder is used.
Thank you sir for detailed information 😊
Thank you very much
thank you explanation was great
In the following example I am getting the output as "References are unequal' but i am expecting the output as "References are equal" since S3 and S4 are created using string class. Can anyone explain me this

if (S3==S4)
SOP("References are equal");
else
SOP("References are unequal");

@@edurekaIN Thank you
toString() method?
toString() method in Java is used to represent any object as a string. This method returns a string representation of an object. To print any object, Java internally invokes the toString method on the object.
This method is used to print array in string form
