I will make this suggestion:
Don't get the bad habit now of naming things so inaccurately.

Quote
Student database[]= new Student[2];
It's not a database. Not even close. Its just an array of Student Objects. So name it such.
```
Student StudentArray[] = new Student[2];
```
Later when you upgrade this project to actually using a database you won't find yourself in the awkward position of having something *named* database and asking yourself..

"Well I have something named database so what should I name my actual database? Hmm... About about 'Array'? That won't be confusing at all"

hahah I am sorry I meant to write What I am doing....nice sense of humor!

Ah..... The youthful days of college when we didn't even know who we were doing. Enjoy it while it lasts. As you get older you at least have to ask their names and pretend like you want to get to know them first.

Does it throw an error?
Does it put the values in the right variables?
You don't need us to tell you if it works or fails. You should be able to see that by looking at the values of the variables.

There are 100 ways to do anything in the programming world. If it works, it works. If you ask 100 coders how they would do something you will get 100 different answers. That doesn't make any one of them more right or wrong than the other. Just different.

You might as well be asking "Am I washing these dishes the *right* way?", or "If I wash these dishes this other way will that work?"

hahah yea in my Student Class it wont work...I am so lost in this assignment and I will go in monday to talk to the head department because I emailed my professor three days ago and got no response and his accent is too heavy to be able to understand him in person. I have been dealong with this code for hours and I dont know who I am doing. This is my first programming class hence I do not have enough programming language to complete this task !

In Topic: must take user input and reverse each sentence that they write

Posted 18 Sep 2011

ok well I redid my entir code and got it to work,, but for some reson it will not reverse the sentences. it is supposed to ask the user how many sentences they want to input and the user inputs a number is than asked to input their sentences ..then it would be like lets say they input I love cats...well then my code is supposed to display Line1: cats I love... and so forth...they only problem I have is reversing the sentences. I did earlier but than changed something and now I dont know why its stuck!

import java.util.Scanner;


public class Main {

    public static void main(String[] args) {
   Scanner keyboard= new Scanner(System.in);

         System.out.print("How many lines would you like to enter : ");
int  answer = keyboard.nextInt();
String s=null;
String temp[];

for(int i=0;i<= answer;i++)
{

System.out.println("Enter your line Please");
s = keyboard.nextLine();
temp=s.split(" ");
  for (int count=1; count <= answer; count++)

   {
            System.out.print("Line" + count + " :" );
            String s1 = keyboard.nextLine();
            System.out.println(s1);
             
    }
    for(int j=(temp.length-1);j>=0;j--){

    System.out.println(temp[j]);
 
    }}}}

In Topic: must take user input and reverse each sentence that they write

Posted 17 Sep 2011

ok well i saw that we can use the deliminter to split sentences...umm this is what i got....im so confused.. I put the sentences in a String and then tried to use the split string thing and got lost once again....

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner keyboard= new Scanner(System.in);
        
        System.out.println ("How many sentences are you inputing?");
        int answer=keyboard.nextInt();

         String[] sentences = new String[answer];

        System.out.println("Please enter your sentences");
          String userSentences=keyboard.next();

          delimiter = "\\.";


          for(int i = 0; i < answer.length; ++i)
       
           {
             String temp = userSentences.split(delimiter);
           }

           for (int count=1; count <=answer; count++)

             {
            System.out.println("Line" + count + " :" + sentences[count] );
              }
    }

}
