    Default What is the difference?

    public class BeerSong {
    	public static void main (String[] args) {
    		int beerNum = 99;
    		String word = "bottles";
    		while (beerNum > 0) {
     
    			if (beerNum == 1) {
    			word = "bottle";
    			}
    			System.out.print(beerNum + " " + word + " of beer on the wall, ");
    			System.out.println(beerNum + " " + word + " of beer.");
    			System.out.print("Take one down.");
    			System.out.println(" Pass it around.\n");
    			beerNum=beerNum - 1;
     
    			if (beerNum == 0) {
    				System.out.println("No more bottles of beer on the wall, no more bottles of beer.");
    				System.out.println("Go to the store and but some more, 99 bottles of beer on the wall.");
    			}
    		}
    	}
    }

    I am new to java. I am referring Head First Java. I am practicing all its codes. There is with the beer Song. I have corrected the error in it. But I have question: What is the difference between mentioning "String word" (in line 3 of code) and only "word" (in line 7).

    Default Re: What is the difference?

    When you code a data type like String before a variable name, you are defining the variable as that datatype.
    Take a look at the tutorial:
    Variables (The Java™ Tutorials > Learning the Java Language > Language Basics)
