Solution
The output of System.out.println('z' - 'a') in Java is 25.
Here's why:
In Java, char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive). When you subtract 'a' from 'z', you're actually subtracting their ASCII values.
The ASCII value of 'a' is 97 and 'z' is 122. So, when you subtract 'a' from 'z' (i.e., 122 - 97), you get 25.
So, System.out.println('z' - 'a') prints 25.
