Thread: Java basic Example

<code=java>

i m giving again a very simple code of odd or even . I want that user should give the value of x and thereafter ,it is checked whether odd or even.

class oddoreven
{
public static void main (String args[])
{
int x;

System.out.println ("Enter an integer to check if it is even or odd ");
if(x%2==0)
System.out.println("you entered an even number ,");
else
System.out.println("You entered an odd number .");
}
}
In this prog user should give the value of x and it is then checked. But i m getting an error that variable x might not have been initialized. Thanks

You don't seem to get input from the user anywhere in your program, and the compiler is smart enough to see that you're not giving x any value. Consider using a Scanner object for this.

can u help me in writing the code for this ?

Hi,
You can use System.in to read values from console.
thus get X value from user and pass that to determine whether odd or even.
