"LANGUAGE".replace('A', '0'); "PROGRAM".compareTo("Program");
Explanation:
"LANGUAGE".replace('A', '0');
Replaces all occurrences of 'A' with '0' in the string.
Result: "L0NGU0GE".
"PROGRAM".compareTo("Program");
Compares the strings lexicographically.
Java uses ASCII values, and the difference in case ('P' in uppercase vs. 'p' in lowercase) gives -32.
