stringbuffer vs stringbuilder java

The StringBuffer and StringBuilder class both produces mutable string objects.
 The main difference between them is that StringBuffer is thread safe;
 StringBuilder is not thread safe.
Comment

string vs stringbuffer

The main similarity between String and StringBuffer class is that both are
thread safe. 
The main difference is that String is immutable; StringBuffer is mutable.

string vs stringbuilder vs stringbuffer

If a string is going to remain constant throughout the program, 
then use the String class object because a String object is immutable.
If a string can change (for example: lots of logic and operations in the construction of the string) 
and will only be accessed from a single thread, using a StringBuilder is good enough.
If a string can change and will be accessed from multiple threads, 
use a StringBuffer because StringBuffer is synchronous, 
so you have thread-safety.
If you don’t want thread-safety than you can also go with StringBuilder class as it is not synchronized.

stringbuffer vs stringbuilder vs string in java

The StringBuffer and StringBuilder class both produces mutable string objects.
 The main difference between them is that StringBuffer is thread safe;
 StringBuilder is not thread safe.
String is immutable and thread safe.
We are using StringBuffer when we are doing parallel
testing since it is a thread safe.

stringbuilder vs stringbuffer

They both mutable, they are exactly same but
String buffer is thread safe so it runs slower
than String builder.
We are using StringBuffer when we are doing parallel

difference between stringbuffer and stringbuilder

StringBuffer:
1. StringBuffer class is synchronized
2. It is thread-safe
3. It is slower than StringBuilder

StringBuilder:
1. StringBuilder class is not synchronized
2. It is not thread-safe
3. It is faster than StringBuffer
