Answer 1

package Loop;

public class Loop
{
public static void main(String[] args)
{
int value = 5;
boolean tag = false;
for(int i = 0;i < 5; i++)
{
for(int j = -value;j <= value;j ++)
{
if(j == 0)
{
continue;
}

if(j == 1 && tag == false)
{
tag = true;
continue;
}

if(tag == true)
{
tag = false;
}

System.out.print(Math.abs(j));
}

System.out.print(" ");
value --;
}
}
}
