Description
1. Type the following file into TextPad adding your name and lab letter. Make sure your file is
called Lab1.java. Don’t copy and paste the code. It does not work if you copied it.
//***********************************************************
// Name: Your Name here

public class Lab1
{
public static void main (String[] args)
{
System.out.println(“This is my first program!”);
}
}
Compile and run the program. What is the output?
2. Mathematical operations::
i. ADDITION. SUBTRACTION, MULTIPLICATION, MODULUS
public class Lab1
{
public static void main (String[] args)
{
//—> Declare two integer variables.
System.out.println(“This is my first program!”);
/* Example*/
System.out.println(“Sum of the two numbers : ”+(num1 + num2));
//—> Add the console outputs for all other operations.
}
}
Let’s do the rest of the operations now! Apply the operators and print the output on the
console.
ii. USING THE MATH CLASS::
Lets calculate the area of a circle using some of the mathematical operations available
in java.lang.Math class.
public class Lab1
{
public static void main (String[] args)
{
//—> Declare two integer variables.
System.out.println(“This is my first program!”);
/* Example*/
System.out.println(“Sum of the two numbers : ”+(num1 + num2));
//—> Add the console outputs for all other operations.
//—> Declare the radius variable and assign a value.
//—> Print the radius.
//—> You may use a separate variable to store the result(area). If you are, then
declare. Else you can simply append.
//—> Print the result.
}
}
The sample output should be like:
This is my first program!
Sum:
Product:
Division:
Modulus:
Value of the radius: 4
Area of the circle: 50.26548245743669
