In an Object Oriented Programming using Java Lab, demonstrating the use of different operators in Java helps students understand how expressions are formed and evaluated within classes and objects. Java provides a rich set of operators that perform arithmetic, relational, logical, assignment, unary, bitwise, shift, and conditional operations. A well-structured program can illustrate how these operators work with variables of different data types and how they influence program flow and decision-making. A simple Java program can be written by defining a class that contains the main method. Inside the main method, different types of variables such as int, double, and boolean are declared and initialized. Arithmetic operators include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). For example, if two integer variables a and b are declared as 10 and 3 respectively, the program can compute their sum, difference, product, quotient, and remainder. The results can be displayed using System.out.println() statements. This demonstrates how arithmetic expressions are evaluated according to operator precedence rules in Java. Relational operators are used to compare two values and return a boolean result. These include greater than (>), less than (<), greater than or equal to (>=), less than or equal to (<=), equal to (==), and not equal to (!=). In the program, comparisons such as a > b or a == b can be evaluated and printed. These operators are commonly used in decision-making statements such as if and while loops. By displaying the results of these comparisons, students can observe how relational operators produce true or false outcomes. Logical operators are used to combine multiple boolean expressions. The main logical
