Step-by-step explanation:

Sample Program:

import java. util. *;

class brainly

public static void main(String args[])

{

System. out. println("Enter your choice : 1 (or) 2);

Scanner demo = new S canner(System. in);

int a = demo. nextInt();

System. out. println();

switch(a)

{

case 1:

int i,j;

for(i = 1; i <=5; i++)

{

for(j = 1; j<=5 - i + 1;j++)

{

System. out. print((char)(j+64));

}

System. out. println("");

}

break;

case 2:

String str="BLUEJ";

for(i = 0 ; i < str. length () - 1 ; i++)

{

for(j = str. length() ; j>i ; j--)

{

System. out. print("");

}

for(int k = 0; k <=i; k++)

{

System. out. print(str. charAt(i));

}

System. out. print("\n");

}

break;

default:

System. out. println("wrong choice");

}

}

}

Output:

Enter your choice: 1 (or) 2
