Java Program to test if a character is uppercase/lowercase/number/vowel [closed]

Answer 1

In Java : Character class has static method called isLowerCase(Char ch) ans isUpperCase(Char ch) , Character.isDigit(Char ch)gives you Boolean value, base on that you can easily achieve your task

example:

String abc = "HomePage";

char ch = abc.charAt(i); // here i= 1,2,3......

if(Character.isLowerCase(ch))
{
   // do something :  ch is in lower case
}

if(Character.isUpperCase(ch))
{
   // do something : ch is in Upper case
}

if(Character.isDigit(ch))
{
  // do something : ch is in Number / Digit
}

Answer 2

This is your homework, so I assume you NEED to use the loops and switch statments. That's O.K, but why are all your loops inner to the privious ones ?

Just take them out to the same "level" and your code is just fine! (part to the low/up mixup).

A tip: Pressing extra 'Enter' & 'Space' is free! (That's the first thing I did to your code, and the problem became very trivial)
