class for_loop
{
public static void main(String args[])
{
int i;
for(i=1; i<=10; i++)
{
System.out.println(i);
}

}
}

PROGRAM TO PRINT MULTIPLICATION TABLE FOR A GIVEN NUMBER
import java.util.Scanner; //Import the Scanner class
class math_table
{
public static void main(String args[])
{
int i,n;
System.out.print("Enter any number: ");

//Method to accept input form the user at run time
Scanner in = new Scanner(System.in);
n=in.nextInt();

// Loop to print multiplication table
for(i=1; i<=10; i++)
{
System.out.println(n + " x " + i +" = " + (n*i));
}
