Java Data Types and Operators: A Comprehensive Guide

The code above demonstrates the use of different data types and operators in Java.

In the code, we declare and initialize variables of different data types:

• 'num1' is an integer with a value of 10
• 'num2' is a double with a value of 3.5
• 'ch' is a character with a value of 'A'
• 'flag' is a boolean with a value of true

We then use these variables in expressions using various operators:

• 'result1' is the result of adding 5 to 'num1'
• 'result2' is the result of multiplying 'num1' by 'num2'
• 'result3' is a boolean indicating whether 'num1' is greater than 'num2'
• 'result4' is the result of adding 1 to the ASCII value of 'ch', and then casting it back to a character

Finally, we output the results of these expressions using the 'System.out.println()' method.
