java program using class and object 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: 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());
