Void means your not returning any values in the method
public void add(int a,int b){
}
If method has return values which means your returning some values to the called of the method

public int add(int a,int b){
{
return a+b;
}

Try this code to see the difference between void() and none void
1) public void getString(){
System.out.print("This is outputed from within the function");
}
2public String getstring(){
String str="This is outputed at the end of the function";
return str;
}

You should not use arguments in void function in java ... in java pertaining to void the compiler doesn't understand the arguments and treats that as invalid... in c it is ok

Code for method parseInt() in java


parseInt(java.lang.String, int)

This code takes two arguments, a string constructor from the Java language and an integer. Its purpose is to parse (meaning de-construct or disassemble into component parts) one data type into another.

Here is an example of a Java program to specify and print out the dimensions of a rectangle, taken from the page http://www.roseindia.net/java/beginners/entervaluesfromkeyboard.shtml:

class Rectangle{
int length, breadth;
void show(int x, int y){
length = x;
breadth = y;
}
int calculate(){
return(length * breadth);
}
}
public class EnterValuesFromKeyboard{
public static void main(String[] args) {
Rectangle rectangle = new Rectangle();
int a = Integer.parseInt(args[0]);
int b = Integer.parseInt(args[1]);
rectangle.show(a, b);
System.out.println(" you have entered these values : " + a + " and " + b);
int area = rectangle.calculate();
System.out.println(" area of a rectange is : " + area);
}
