please explain why the output in this code as follows. I really don't understand.

Question

String str1 = "JAVA";
String str2 = " java ";
int n = str1.compareTo(str2);
System.out.println(n) ;
// -32

Answer 1

compareTo() returns difference of character values...
Ascii J = 74
Ascii j = 106
74 - 106 = -32

Answer 2

Answer 4

If you would sort theese two Strings, the negative value means that JAVA comes before java:
JAVA, java
As a rule: if you compare two Strings or other objects:
value < 0 -> object1 < object2
value = 0 -> objects are equal
value > 0 -> object1 > object2
