Скачать или смотреть Floats and Double in Java

Java supports several primitive data types, including 'int' for integers and 'float' for single-precision floating-point numbers.

A small code snippet to demonstrate the use of constant, integer and float is given below.

public class PrimitiveDataTypes {
// Constants
public static final int MAX_SCORE = 100;
public static final float PI = 3.14159f;
public static void main(String[] args) {

// Integer variable
int score = 85;
// Float variable
float radius = 5.5f;

// Calculate the area of a circle using the float constant PI
float area = PI * radius * radius;
// Check if the score is a perfect score using the integer constant MAX_SCORE
boolean isPerfectScore = score == MAX_SCORE;

// Output the results
System.out.println("Score: " + score);
System.out.println("Maximum Score: " + MAX_SCORE);
System.out.println("Radius: " + radius);
System.out.println("Area of the Circle: " + area);
System.out.println("Is Perfect Score? " + isPerfectScore);
}
}
