[WHAT IS WRONG] Inputting 4 float numbers, either (+ or - ); but only add the negative and then printing the sum, two decimal.

I advise you to start sololearn's Java course, that's no doubt, you're not aware of it Variable declaration is one of the first things to learn. float a=1,n,s=0; Here is missing the name of the variable that will be assigned the value 1. Better name it a, to fix your loop error

I don't know what you expecting through this program first mistake is in variable declaration u assigned 1 to float here variable is missing then inside loop u used if condition your condition will be failing for positive Integers

See this one import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner in=new Scanner(System.in); float a=1,n,s=0; n=in.nextFloat(); System.out.println(); while(a<=5) { if(n<0) s=s+n; if(n>0) s=s+n; a++; } System.out.println(" %.2f "+s); } } Note : first do always dry run this a good practice how your program flowing and try to solve your errors self read them properly and try to fix it one by one

Hi Erlénio.RS you are right. I just started learning coding not long ago. I just wanted to learn java for hobby and the problems that I asked here...I just found them on the internet. I am not properly taught, so I hope you understand. Thank you for the advice though. Appreciate it. Have a nice day
