java class definition code example
Example 1: what is a class
A class is a block of code that holds various functions. Because they
are located inside a class they are named methods but mean the samne
thing. In addition variables that are stored inside a class are named
attributes. The point of a class is to call the class later allowing you
to access as many functions or (methods) as you would like with the same
class name. These methods are grouped together under one class name due
to them working in association with eachother in some way.
Example 2: How to make a class in Java?
public class Object {
public int a = 1;
private int b = 5;
int c = 0;
void setB(int B)
{
b = B;
}
int getA()
{
return b;
}
}
Example 3: java class
public class Lightsaber {
private boolean isOn;
private Color color;
public Lightsaber(Color color) {
this.isOn = false;
this.color = color;
}
public Color getColor() {
return color;
}
public boolean getOnStatus() {
return isOn;
}
public void turnOn() {
isOn = true;
}
public void turnOff() {
isOn = false;
}
}
public class test {
public static void main(String[] args) {
Lightsaber yoda = new Lightsaber(green);
yoda.turnOn();
}
}
Example 4: using class in java
public class HelloWorld {
public static void main(String[] args) {
class User{
int score;
}
User dave = new User();
dave.score = 20;
System.out.println(dave.score);
}
}
Example 5: java class
public class TestClass {
private int id = 111;
public TestClass(){
super();
}
public void test(){
}
}
Example 6: using class in java
class Number {
int number;
public boolean isSquare(){
double squareRoot = Math.sqrt(number);
if(squareRoot == Math.floor(squareRoot))
{
return true;
} else {
return false;
}
}
public boolean isTriangular(){
int x = 1;
int triangularNumber = 1;
while(triangularNumber < number){
x++;
triangularNumber = triangularNumber + x;
}
if(triangularNumber == number){
return true;
} else {
return false;
}
}
}
Number myNumber = new Number();
myNumber.number = 16;
System.out.println(myNumber.isSquare());
