for two positive integers:
public static int gcd(int i1, int i2) {
// using Euclid's algorithm
int a=i1, b=i2, temp;
while (b!=0) {
temp=b;
b=a%temp;
a=temp;
}
return a;
}
simple program for recursion in java
Declaring a method is when you code for what the method will perform. When you call a method, you are using the method you have written in another part of the program, (or inside the method if it is recursive).
Use the following function: int gcd (int a, int b) { while (b != 0) { a %= b; a ^= b ^= a ^= b; } return a; } Note that a ^= b ^= a ^= b is an efficient method of swapping two values.
Java program without mainWe need a main method for executing a program.But YES we can write a program without using main() method.TRICK 1 of 2 :: while writing applets in java we don't use main... we use init() method instead.TRICK 2 of 2 :: using 'static' we can write a program whic will execute successfully and output the desired message on screen. Here it is :: class Mohit{ static { System.out.println("This java program has run without the main method"); System.exit(0); } } -->save the program as Mohit.java to compile::javac Mohit.java (in command prompt) to run ::java Mohit(command prompt) output will be ::This java program has run without the main methodWhoa!!!!! we are done.;)
When you start your xxxx.class it will execute its 'public static void main (String args[])' method. Any other main methods won't be executed, only if your program explicitly calls them.

i love u darling
i need this answer
biggest3 (a,b,c) = biggest2 (a, biggest2 (b,c))

Recursive refers to using a rule or procedure that can be applied repeatedly.
When you start your xxxx.class it will execute its 'public static void main (String args[])' method. Any other main methods won't be executed, only if your program explicitly calls them.
