I'm very sorry if this is not permitted.. How can I write a java program to compute fractions and display the result exactly( as fraction too) without turning it to decimal or rounding off/up.. Do I need to import any java package??

Dayuum!!

The grand master teacher told me never to laugh at the next black person, but this is hella funny.

Anyway, FOBs always jump the gun, and most of them don't know how to act.

Hopefully, ol'boy will acclamatise with time and stop disgracing black folks.

However, according to scientists (lol), the odour has 2/3 year life span - he'll have to live with that for now.

The Op has done justice to the problem but the question is somehow. If what you mean is: a program to take ten integers from the user and sum them, then the solution goes thus:

import java.util.Scanner;      //imports the Scanner class

public class SumIntegers{
          
                    public static void main(String args[]){
                         Scanner input = new Scanner(System.in);    //creates an object of the Scanner class to take input from keyboard
                         int number;    //the integer declaration
                         int sum = 0;   //declares the sum integer and initialize it to zero
                         
                          for(int i = 1; i <= 10; i++){              //repeat the enclosed instructions 10 times
                        
                              System.out.println("Please enter an integer:";
                              number = input.nextInt();     //takes the integer from the user
                              sum = sum + number;         //performs the addition operation
                          
                         }

                      System.out.print("The sum of the ten integers entered is: " + sum);


                    }

}

JAGZZ:
nnasino, Please help with this question: Write a program to sum ten integers using Java

class Sum{
    public static void main( String[] args){
    int sum = 0;
    for(int I = 1; I <= 10; I++){
       sum += I;
    }
    System.out.println("Sum of first ten numbers: " + sum);
}
}

BizBloke:


That's fine, Nnasino.

The charges levied on the vendor site, including the weight value in dollars and the exchange rate equivalent in naira has to be borne by the client.

Thanks and have a good day.

sconp:
This was what I did for the simple interest. I need corrections o.

public class Simpleinterest {

public static void main (String[] args) {
double principal = 2000;
double rate = 5;
double time = 5;

double result = (principal * rate * time)/(100);

System.out.println(result);

forgive the spacing typing with my nokia phone.
Correction pls.

sconp:
well done op. I am definitely following. I was able to run the hello world program and the continuous addition program.
They were successful.

I would try my hands on the simple interest tonight or tomorrow and paste my result here.
Keep the good work on bro.
Thanks a bunch.

mgb4reel:
If i may humbly request from the OP if i could also help along the teaching process; at least, give answers to questions, give suggestions on understanding some concepts better? I have been coding in java for a while now and i understand it quit well. Will really like to help the beginners too.

basbone:
I dont want to spoil this thread but why is java designed to first import, instantiate and declare the system.in before you use it? Thats why i fled from java. In C#, you just use Console.ReadLine(), and thats it.

int integerNumber;

    public static void main(String[] args){
        int result = 1; //declare and initialize result with 1
        result = result + result; // line 3
        System.out.println(result);
        result = result + result;
        System.out.println(result);
        result = result + result;
