string vs stringbuffer code example

Example 1: what is stringbuffer

StringBuffer class produce mutable string object
and it is thread safe.
We are using StringBuffer when we are doing parallel
testing since it is a thread safe.

Example 2: 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.

Example 3: 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.

Example 4: 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
testing since it is a thread safe.

Example 5: difference between 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.
