Hi, I am having some trouble with arrays.
I have an array of 5 elements. The values of the array are integers. I want to validate the input using an if statement. (the numbers must be between 10 and 100).
I then want to compare the user input to the unique numbers in the array using a for statement. I only want to store the new number if it is unique.
Please help, I'm desperate!!

This is the code so far
public class array
{
//This gerts 5 unique numbers from the user
public void getNumbers()
{
Scanner input = new Scanner( System.in );
new int[5] //Constructing the array
int[] number = new int[5]; //Declaration of the array variable
int count = 0; // Number of uniques read
int entered = 0; // Number of numbers entered
//Checks whether the number entered has already been entered into the array, if it has then the following message is displayed:
while( entered < numbers.length )
{
System.out.print( "Enter number:" );
int[0] = input.nextInt;
if (int[] == number)
public class array
{
//This gerts 5 unique numbers from the user
public void getNumbers()
{
Scanner input = new Scanner( System.in );
new int[5] //Constructing the array
int[] number = new int[5]; //Declaration of the array variable
int count = 0; // Number of uniques read
int entered = 0; // Number of numbers entered
//Checks whether the number entered has already been entered into the array, if it has then the following message is displayed:
while( entered < numbers.length )
{
System.out.print( "Enter number:" );
int[0] = input.nextInt;
if (int[] == number)
I'll go through each of the errors I see.
1)
This line does nothing useful and is missing a semicolon. You should remove the line completely.
2)
This line should be using the variable name, not the variable type to reference the array. Also, you're missing parentheses after
3)
I have no idea what you're trying to do here.

nextInt , also, you want to change the index each loop so you don't rewrite over element 0. Probably should be: number[entered] = input.nextInt(); 3)
if (int[] == number) I have no idea what you're trying to do here.
