Scanner to TextIO question

I need to add a value and input it directly into an array using TextIO. I kn开发者_JAVA百科ow that if I was using Scanner I would use the in.nextDouble() function, but how would I do it using TextIO?

 TextIO.put("Enter credit hours:");
 creditHour[sem][grd]+=in.nextDouble(); //I have to use TextIO here.

Thanks in advance,

Found it.

array [i][r] = TextIO.getlnDouble();
