Basic JAVA ~easy to understand~

here is some codes in java, this is the first part of two parts. also check out these programs in cpp, cobol and also c# and vb.net. i will be posting… please replay if this is help ful.

I USED A PROGRAM CALLED ECLIPSE TO DO THEM. DOWNLOAD IT FOR FREE. IT's COOL TOO!!!

public class ass1 {
	public static void main( String args[] )	
{
	double AmountoPay;
	double NumberoPeriod;
	double total;
	AmountoPay =1700.00;
	NumberoPeriod = 26;
	System.out.print("Amount of pay per pay period is $");
	System.out.print(AmountoPay);
	System.out.print("\n");
	System.out.print("\nNumber of pay periods per year is ");
	System.out.print(NumberoPeriod);
	System.out.print("\n");
	total = AmountoPay * NumberoPeriod;
	System.out.print("\nThe annual pay is $");
	System.out.print(total);
	System.out.print("\n");
	System.out.print("\n");
	System.exit( 0 );
}
}

public class ass2 {
	public static void main( String args[] )	
{	double perc = .62;
int Tsale = 4600000;
double PredSal;
PredSal = perc * Tsale;
System.out.print("Predicted East Coast Sales = $");
System.out.print(PredSal);
System.out.print("\n");
System.out.print("\n");
System.exit( 0 );
}
}

result = "THe total Avg. is " + ( (total1 + total2 + total3)/3 );

 System.exit( 0 ); // terminate application
 } 
 }

public class ass3 {

 }

so, what exactly is the point of this and why didnt you just try and make an article with some sort of explaination to go with it?

You can use System.out.println instead of putting a /n at the beginning of every new statement.

Oh, and you can use the concantenation symbol (+) to put some things together. For example, you have:

System.out.print(StateSalestax);```
which could be rewritten as:

```markupSystem.out.print("The county sales tax = $" + StateSalestax);```
which effectively eliminates a line of code.

I'm still learning Java, so those are the only things I noticed.  Hope I helped and didn't confuse anyone too much.
