Task 1:
Task 1:
Assignment – 0: static, non-static
- Create a class Called Theatre.
- Declare below global variables in it.
2.1. String movieName
2.2. int movie_time - Add main method
- Inside main method, create two instances (objects),
4.1 movie1
4.2 movie2 - For instance movie1, add ‘Jailer’ as movieName and 630 as movie_time
- For instance movie2, add ‘Leo’ as movieName and 7 as movie_time
- Create and define a method as below.
public void watch_movie()
{
System.out.println(“Watching ” + movieName);
System.out.println(“Show Time is ” +movie_time);
} - Call above method using both the instances – movie1, movie2.
- Go through and record your observations.
Source Code :
public class Theatre1
{
String movieName;
int movieTime;
public static void main (String args[])
{
Theatre1 movie1 = new Theatre1();
Theatre1 movie2 = new Theatre1();
movie1.movieName = “jailer”;
movie1.movieTime = 630;
movie2.movieName = “leo”;
movie2.movieTime = 720;
movie1.watch_movie();
movie2.watch_movie();
}
public void watch_movie()
{
System.out.println(“watched: ” + movieName + ” showtime: ” + movieTime);
}
}
Output:
watched: jailer showtime: 630
watched: leo showtime: 720
Task 2:
return statement
- Create a class called EB_Reading
- Have main method in it.
- Create an object called assessor.
- Using assessor instance, call a method named ‘reading’.
- ‘reading’ method should return consumed units in int.
- Store the returned value as ‘consumed_units’.
- Using the same ‘assessor’ instance, call a method
named as ‘calculate’. - Pass ‘consumed_units’ as argument to calculate.
- Based on the consumed_units value, find out How much Customer should pay.
- Print Payment value.
Source Code:
public class EbReading
{
public static void main (String args[]){
EbReading assessor = new EbReading();
int Consumed units = assessor.reading();
System.out.println(“CU”+ Consumed units);
assessor.calculate(Consumed units);
}
public int reading()
{
int unit1 = 100;
return unit1;
}
public void calculate(int Consumed units)
{
int payment = Consumed units*10;
System.out.println(“Pay: ” + payment);
}
}
Output:
CU: 100
Pay: 1000
Task 3:
Add Methods in Calculator
public class Calculator
{
public static void main(String[] args)
{
Calculator calc = new Calculator();
calc.add();
}
public void add()
{
System.out.println(10+20);
}
}
//subtract()
//multiply()
//divide()
Source code:
public class Calculator1
{
int a = 10;
float b = 20.5f;
public static void main (String args[])
{
Calculator1 calc = new Calculator1();
calc.add();
calc.sub();
calc.mult();
calc.div();
}
public void add()
{
float c = a+b;
System.out.println(“Addition: “+ c);
}
public void sub()
{
float c = a-b;
System.out.println(“subtraction: “+ c);
}
public void mult()
{
float c = a*b;
System.out.println(“multiply: “+ c);
}
public void div()
{
float c = a/b;
System.out.println(“divition: “+ c);
}
}
Output:
Addition: 30.5
subtraction: -10.5
multiply: 205.0
divition: 0.4878049
