If you "extract variable", and "replace all occurrences" on
"a" + "b"
in the code below,
IDEA will only detect 2 occurences, and not the 4 possibles ;
Before:
System.out.println(
"a" + "b"
+ "a" + "b"
);
System.out.println(
"a" + "b"
+ "a" + "b"
);
After:
String COMMON = "a" + "b";
System.out.println(
COMMON
+ "a" + "b"
);
System.out.println(
COMMON
+ "a" + "b"
);
