Objectives:
- How to use switch case in Java?
- How to use switch case with string in Java?
- How to pass string literals in switch case in Java?
Source Code:
public class SwitchWithStringExample
{
public static void main(String[] args)
{
String str = "two";
switch(str)
{
case "one":
System.out.println("one");
break;
case "two":
System.out.println("two");
break;
case "three":
System.out.println("three");
break;
default:
System.out.println("no match");
} // switch close
} // main close
} // class close
Steps to run above Java code:
Consider that we have saved code at C drive (c:\>) and the file is saved as SwitchWithStringExample.java
- Compilation : c:\> javac SwitchWithStringExample.java
- Interpretation : c:\> java SwitchWithStringExample
Output:
two

// Old way
System.out.println("Old way");
for(int i=0; i<a.length;i++)
{
System.out.println(a[i]);

Objectives:
- How to find the area of a circle in Python?
- How to find the circumference of a circle in Python?
- How to find the area and circumference of a circle in Python?
Python Code:
print("Enter radius of circle")
rad = input()
r=float(rad)
area = 3.14 * r * r
circumference = 2 * 3.14 * r
print(area)
print(round(circumference, 2))
Steps to Run the above code:
- Navigate to the folder/directory where you have saved your python code or file.
- Here I have considered that python file is saved on “c:\>” and the File name is “Circle.py
- Just type the following command now to execute the Python program: c:\> python Circle.py
Download code:
- Navigate to GitHub repository and download the code from here: Circle.py

Objective:
- How to write Hello World in JavaScript?
- How to write Hello World in JS?
- How to print Hello World in JavaScript?
- How to print Hello World in JS?
Source Code :
Here is the sample code for you:
<html>
<body>
<script language = "javascript" type = "text/javascript">
document.write("Hello World!")
</script>
</body>
</html>
Git Hub:
You can also download this code from link given here : Hello World in JS
Pattern 3 :
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
Java Code for above pattern :
import java.util.Scanner;
public class Pattern3
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
//Taking rows value from the user
System.out.println("How many rows you want in this pattern?");
int rows = sc.nextInt();
System.out.println("Here is your pattern....!!!");
//Printing upper half of the pattern
for (int i = 1; i <= rows; i++)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
//Printing lower half of the pattern
for (int i = rows-1; i >= 1; i--)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}
System.out.println();
}
//Closing the resources
sc.close();
}
}
Output :
1
1 2
1 2 3
