That's a good start. I'll tryto help some more.

1) you need to include a case for the space between words.

You probably didn't try to compile this because

Switch(..)

is wrong, it's

switch(..)

Here's how I would do it:

declare a char array holding all the letters:

char[] ltr = {'a','b','c','d',..'z' ' '};

that last char is the space

Also define a string array to hold the converted values:

String[] morse = {".-", ..." "}

make sure that ltr and morse are the same length

once you get your string input then

for( int k=0; k
...for( int j=0; j
......if( input.charAt(k) == ltr[j] ) System.out.print(morse[j]);

...}

}

That should do it. Quite a bit simpler than all that case stuff, no? There are some refinements that could be made but code this up and come back with your code and I'll help some more.

+add

If you want to keep your switch logic then keep the outer k loop and replace what's inside with

String outStr;

switch(input.charAt(k)){

case 'a':

outStr = ".-";

break;

case 'b':

...etc

}

System.out.print( outStr );

I'll need to see your attempt at this before I offer any more help.

My program is supposed to translate a sentence "a million dollars" into morse code.

My attempt at it.

Not sure where to go from here.

Your Morse code looks okay. It's harder for me to read written down than to hear it. I was a Amateur Ham radio operator about 47 years ago. So I am a little rusty. I could send and receive 30 wpm. Now I might do 5 LOL.
