java create a class code example
Example 1: 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 2: 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 3: classes in java
public class MathTest {
public static void main(String[] args) {
class MathAdd {
int num1;
int num2;
public int addNumbers() {
int addThemUp = num1 + num2;
return addThemUp;
}
}
MathAdd addition = new MathAdd();
addition.num1 = 10;
addition.num2 = 20;
System.out.println(addition.addNumbers());
}
}
Example 4: java class
public class TestClass {
private int id = 111;
public TestClass(){
super();
}
public void test(){
}
}
Example 5: using class in java
public class HelloWorld {
public static void main(String[] args) {
class Number{
int number;
public boolean isPos(){
if(number > 0){
return true;
} else {
return false;
}
}
}
Number myNumber = new Number();
myNumber.number = 7;
if(myNumber.isPos()){
System.out.println(myNumber.number + " is positive!!!");
} else {
System.out.println(myNumber.number + " is not positive!!!");
}
}
}
