String comparison in Java

I just tried it and found that this is actually true.

String a = "abc ";
String B = "abc ";
System. out. println (a = B );

Check that only one string with the same value is saved in Java, because the string remains unchanged. If this is the case,

String a = new String ("abc ");

String B = new String ("abc ");

Then compare a = B, and the display is false, because these are two different objects.

In this case, it seems that equals is recommended when the comparison value is equal.

String a = new String ("abc ");

String B = new String ("abc ");

A. equals (B );

Returns true.

It seems safer.
