Java Exercise
In this exercise, you will create a Java program that uses various Operators and Expressions to perform calculations and evaluate conditions. You will learn to work with:
- Arithmetic operators: addition, subtraction, multiplication, division, and modulo.
- Relational operators: comparing values such as greater than, less than, and equality.
- Logical operators: combining conditions with
&& (AND) and || (OR).
- Assignment operators: modifying and updating variable values.
Instructions:
- Declare two numeric variables and perform arithmetic operations on them.
- Use relational operators to compare values and display the results.
- Apply logical operators to evaluate combined conditions.
- Display the results to the console using
System.out.println().
This exercise will help you understand the use of Operators and Expressions in Java, which are essential for programming logic and decision-making in code.
View Example Code
public class JavaOperators {
public static void main(String[] args) {
// Variable declaration
int a = 10;
int b = 5;
// Arithmetic operators
int sum = a + b;
int subtract = a - b;
int multiplication = a * b;
double division = (double) a / b;
int modulo = a % b;
// Relational operators
boolean isGreater = a > b;
boolean isEqual = a == b;
// Logical operators
boolean condition1 = (a > 0) && (b > 0);
boolean condition2 = (a < 0) || (b < 0);
// Display results in console
System.out.println("Sum: " + sum);
System.out.println("Subtraction: " + subtract);
System.out.println("Multiplication: " + multiplication);
System.out.println("Division: " + division);
System.out.println("Modulo: " + modulo);
System.out.println("Is A greater than B?: " + isGreater);
System.out.println("Is A equal to B?: " + isEqual);
System.out.println("Are both numbers positive?: " + condition1);
System.out.println("Is either number negative?: " + condition2);
}
}
Output:
Addition: 15
Subtraction: 5
Multiplication: 50
Division: 2.0
Modulo: 0
Is A greater than B?: true
Is A equal to B?: false
Are both numbers positive?: true
Is either number negative?: false
This code demonstrates the use of arithmetic, relational, and logical operators in Java, allowing you to understand how to perform calculations and evaluate conditions in a program.
