Thread: Listing the alphabet in lower and uppercase

Ok, so basically I need to d this java application for an assignment. It says Write a java program that uses the ASCII codes and a for loop in a METHOD Alphabet() to display the alphabet in the following format.

I'm not too good at java but this is what i got so far.

{
public static void main( String args[] )
{
 
char upper;
char lower;
 
System.out.printf( "%s%20s\n", "UPPERCASE", "LOWERCASE");
for ( upper = 'A'; upper <= 'Z'; upper++ )
 
{
System.out.print(upper);
System.out.println();
}
 
 
 
}
}

Problem is.. I'm not even using ASCII or the Alphabet method. I need some serious help here, and i know some of you might not one to help but to those who want your help will be appreciated.

I also have it this other way;

This way it shows the alphabet but i can't manage to but them in two different rows one saying UPPERCASE and the other saying lowercase

public class Alphabet {
public Alphabet() {
for ( int i = 65; i < 91; i ++ ) {
System.out.println("Upper Case\n"+(char)i + " " + (char)(i+32));
}
}
public static void main(String [] args) {
new Alphabet();
}
}

The output has to be like this

UPPERCASE lowercase
A a
B b
C c
. .
. .
. .
Z z



With the second code i already have a similar output... but i can't seem to add the headers UPPERCASE and lowercase.

can anyone help me with this? Thanks in advanced.

You need to output the headers before going into the loop, so they only get printed once.

Yeah i already solved it... for some reason i failed to realize that if i left the headers in the loop they would keep repeating themselves
