You can store it as a multipart value or you can convert it into base64
public static void main(String[] args) {
StringBuffer sb1=new StringBuffer(“abc”);
StringBuffer sb2=new StringBuffer(“xyz”);
StringBuffer sb3=new StringBuffer(“abc”);
sb1=sb2;
sb2=sb3;
sb3=sb1;
System.out.println(sb1==sb2);
System.out.println(sb3==sb1);
System.out.println(sb2==sb3);
System.out.println(sb1);
System.out.println(sb2);
System.out.println(sb3);

How answer is false true false

Comparison
In stringbuffer .equals method is not overridden then object class .equals() method will be called.
It is reference comparison

Read about string pool
Stringbuffer objects are also Store in scp?
No, but s buffer and so on s builder is an abstraction over string
Ok
i think id lied to you, its not about strings, it`s abount pointers only
Ok
you can replace string buffers with just new Object, and have same result
And I want to saveMessage according to user by their ids
