Task 1:

Task 1:
Assignment - 0: static, non-static

1. Create a class Called Theatre.
2. Declare below global variables in it. 2.1. String movieName 2.2. int movie_time
3. Add main method
4. Inside main method, create two instances (objects), 4.1 movie1 4.2 movie2
5. For instance movie1, add 'Jailer' as movieName and 630 as movie_time
6. For instance movie2, add 'Leo' as movieName and 7 as movie_time
7. Create and define a method as below. public void watch_movie() { System.out.println("Watching " + movieName); System.out.println("Show Time is " +movie_time); }
8. Call above method using both the instances - movie1, movie2.
9. 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

1. Create a class called EB_Reading
2. Have main method in it.
3. Create an object called assessor.
4. Using assessor instance, call a method named 'reading'.
5. 'reading' method should return consumed units in int.
6. Store the returned value as 'consumed_units'.
7. Using the same 'assessor' instance, call a method named as 'calculate'.
8. Pass 'consumed_units' as argument to calculate.
9. Based on the consumed_units value, find out How much Customer should pay.
10. 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
