- Comments Off on Passing String in Switch Case in Java
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

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();
}
}
