JAVA Program to print following patterns with the help of users choice statement(switch-case)
{
public static void main() {
Scanner Sc=new Scanner(System.in); System.out.println(“Enter 1 for number pattern”); System.out.println(“Enter 2 for alphabetical patter “); System.out.println(“Now give your choice “); int choice=Sc.nextInt();
switch(choice)
{
case 1: for(int i=5;i>=1;i--)
{
for(int j=1;j<=I;j++)
{
System.out.print(j+” “); }
System.out.println();
}
break; case 2: char jh=’A’;
while(jh<=’E’)
{
char kh=’A’; while(kh<=jh)
{
System.out.print(kh+” “); kh++;}
System.out.println();
jh++;
} } } } }
Enter 2 for alphabetical pattern Now give your choice 1
