use while loop to output the numbers and their square between 1 and 10
i'm trying to use while loop to output the numbers and their square between 1 and 10.
Here's my codes:
import java.io.*;
import java.math.*;
public class Square
{
public static void main(String[] args) throws IOException
{
double num = 1;
while(num <= 10)
{
num = Math.pow(num, 2);
System.out.println(num + " ");
}
}
}
i don't know why my output is
1.0
1.0
1.0
1.0
.
.
.
.
..
it just keeps going forever!!
why?
how do i fix it?

Split mind!
increment "num" inside the loop
double num = 1;
while(num <= 10)
{
num = Math.pow(num, 2);
System.out.println(num + " ");
num += 1.0
}
double num = 1;
while(num <= 10)
{
num = Math.pow(num, 2);
System.out.println(num + " ");
num += 1.0
}

sorry, another question:
how do i make the output horizontally?

hi crystalfish0318,
>>sorry, another question:
Thats fine~
>>how do i make the output horizontally?
As you probably aware, that "println" actually prints the parameter + a \n. Whereas, "System.out.print" jsut prints out the parameter without a \n being attached at the end. So in this case, use print instead of println.
thank you
