public class Calculator extends Frame implements ActionListener,...

My code is not working for some reason, help? When I try to compile, it says that there are 34 errors, many stating "illegal start of expression" and "';' expected"

What's the "CreateException class" ?? Mainly it does not read the quotes and says I should have semicolons in places that seem strange to have them in.

There is an issue with part of my program, I get two errors.. And I have no idea how to fix it. Here is what I have for the code:


class Customer{
private String name;
private int age;
public...

This is what I have so far:

class Customer{
private String name;
private int age;
public Customer(String n, int a)throws CreateException{
if(0<a<125){
Name=n;
Age=a;
throw new...

public class BinarySearch
{
public static final int = 45.3;
public static int binarySearch (Integer [] a, int x)
{
int low=0;
int high = a.length; 45.3;
int mid;
...

What does a. length mean?

public class BinarySearch
{
public static final NOT_FOUND = -1;
public static int binarySearch (Integer [] a, int x)
{
int low=0;
int high = a.length - 1;
int mid;
...

Do I need to write an array to start it, to end it, or not at all? ~ Sorry, I kept getting errors with the code I had.

So I need to do this:

A Java program to find the value 45.3 from this list ={-3,10,5,24,45.3,10.5} using the binary search method.

And I have absolutely nothing. I need help as soon as...

Okay, I re wrote it and now I only have 1 error:

class SingleDimensionalArray
{
public static void main(String args[])
{
int a[]= new a[10];
a[0] = 1;
a[1] = 2;
a[2] = 3;

And when I compile that program it comes up with 4 errors:

SingleDimensionalArray.java:6: not a statement
a[]=(1,2,3,4,5,6,7,8,9,19);
^
SingleDimensionalArray.java:6: ';' expected...

What is an index?

This is what I'm supposed to do:

A Java program using single dimensional array. Have a list of 10 numbers and fetch a value based on the index.

The second part is not very clear, so I ended up...
