Write a program to calculate the area of a rectangular. You need to define following method in the Rectangular class:

public void calculateArea(double l, double h)

public double findLength()

public double findHeight()

public void setLength(double l)

public void setHeith(double h)

```class CalculateArea
{
double l, h;
public void calculateArea(double l, double h){
double area=l*h;
System.out.println("Area of Rectangle is: "+area);
}

public double findLength(){
return l;
}

public double findHeight(){
return h;
}

public void setLength(double l){
this.l=l;
}

public void setHeight(double h){
this.h=h;
}

public static void main(String[] args)
{
CalculateArea area=new CalculateArea();
area.setLength(5);
area.setHeight(4);
double len=area.findLength();
double hgt=area.findHeight();
System.out.println("Length is: "+len);
System.out.println("Height is: "+hgt);
area.calculateArea(len,hgt);
}
}
```
