Difference between "concat" and "+"

[lotus18]

Hello Java World

Can anyone tell me what's the difference between the

1. concat and +?
2. append and insert?

Closely study the following little example and read the API documentation:

[code=java]
String ss= "abc";
System.out.prin tln("abc" == ss+"");
System.out.prin tln("abc" == ss.concat(""));
[/code]

kind regards,
