Frage 306. What is literals in core java?
Java Literals are syntactic representations of boolean, character, numeric, or string data. Literals provide a means of expressing specific values in your program. For example, in the following statement, an integer variable named count is declared and assigned an integer value. The literal 0 represents, naturally enough, the value zero.
int count = 0;
Boolean literals: true, false
Some numeric literals: 1233, 554.334, -78
