Printing Fibonacci Numbers - Illegal Start Of Expression
Nov 1, 2014
Here is my program and results and I am having a error on line 38 which is "public static long fib01(long paramLong)" The program does give me my results but I am trying to correct there error.
public static void main(String[] args) {
{
System.out.print("
" + String.format("%-10s", new Object[] { "Index" }));
System.out.print(String.format("%-15s", new Object[] { "Fibonacci01" }));
System.out.print(String.format("%-15s", new Object[] { "Fibonacci02" }));
System.out.println(String.format("%-15s", new Object[] { "Fibonacci01" }));
I am getting the error "Line 54, illegal start of expression". Line 54 is where my "for" starts. It was running ok earlier, now I can't get this error to go away?
Lines 7 , 10 ,13 .... All have a Illegal Start of Expression error.
[color=blue]private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { Random rd = new Random(); int random = 0; random=rd.nextInt(6)+1; switch(random){
why the complier is giving the following error message "illegal start of expression" once it reach the countSpaces method.The way I see it (and I am obviously seeing it wrong), the code is public since why not, int since it returns an int # and the method has return int in it, and static I am not too sure but I get the same error message whether or not it is included
public static void main (String args[]) { Scanner in = new Scanner(System.in); String sentence; System.out.println("type a sentence"); sentence = in.nextLine(); countSpaces (sentence);
Why does this not work? I get an ']' expected at the y in the fourth line of code and an illegal start of an expression at the actual ] in the same line
int y = 0; JTextField response[] = new JTextField[10]; while(y < 10) { JTextField response[y] = new JTextField(7); add(response[y]); response[y].addItemListener(this); ++y; }
I'm working on a program and can't seem to fix my for loop error.I get an error at the for loop line saying illegal start of expression and i don't know how to fix it:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */
I need to know why this program is giving me error (illegal start of expression). What must i do to stop the error?
//Read a character from keyboard class Kbin{ public static void main(String[]args){ throws java.io.IOException{ char ch;
System.out.print( " Press a key followed by ENTER: "); ch = (char) System.in.read();//read character from keyboard System.out.println( "Your key is: " + ch); } } }
public static void main(String[] args) { Scanner Keyboard = new Scanner(System.in); System.out.print("Please enter your name."); String name = Keyboard.next(); name = "name";
I'm attempting to create a program that employs a method to count the number of 7s a user puts as an input into the program. I'm just getting started, but I'm getting an error when I try to implement a main method that says "Illegal start of expression"
What adjustments could I make to eliminate this error message?
// Add a main method here. public static void main(String[] args) { //Error occurs here public static int countSevens(int n) { // 0. Clean-up. Get rid of any minus signs as that is not a digit. n = Math.abs(n);
I'm working through Head First Java, and I'm struggling with the chapter 6 magnet exercise on page 161. I've checked my answer countless times, and it appears to match the book's code, but when I try to run it on my computer I'm getting an error. It says:
error: <identifier> expected System.out.println^(" "); and
error: illegal start of type System.out.println(^" ");, both for line 32.
I cannot seem to figure out what is different about my code!!
import java.util.*;
public class ArrayListMagnet { public static void main (String [] args) { ArrayList<String> a = new ArrayList<String>(); a.add (0, "zero"); a.add(1, "one"); a.add(2, "two"); a.add(3, "three");

Also, I'm not sure if this has anything to do with the above errors, but I'm getting a third error message for line 34 saying:
Public static boolean updateNetMap(String filepath, String nodename){
// check the file pointed by filepath to have entry for nodename. // if it is there, get the start line no and end line no // Based on the line nos, need logic to remove the contents from the file. }
Below is the sample node entry, which we need to identify and delete (here nodename is WAS_CD1):
I need a regular expression in java for phone number which that does not allow any character special character only numbers should be allowed.. My sample program is
import java.util.regex.Matcher; import java.util.regex.Pattern; public class c { public String removeOrReplacePhoneNumber(String input) { if (null == input) return input;
so for class I have an assignment that involves printing distinct numbers. the assignment is as follows: Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly on space. Here is what the input and the output are supposed to look like:
Input: Enter Ten Numbers: 1 2 3 2 1 6 3 4 5 2 Output: The Number of distinct numbers is 6 The distinct numbers are: 1 2 3 6 4 5
So far I have the entire code but right now it only prints out the distinct numbers, not how many distinct numbers there are. what that part of the code would look like?Here is my current code:
public class exer75 { public static void main(String[] args) { java.util.Scanner input = new java.util.Scanner(System.in); //create scanner system System.out.println(""); System.out.print("Enter Ten Numbers: "); //prompt the user to enter 10 numbers int[] values = new int[10]; //create an array to hold the numbers
The assignment is to make a program that prints the number of prime numbers in a range. This is what i have so far. The output is a list of 2s. I created the for loop to cycle through the range of 17-53 and nested a while loop within to test each incident of the for loop to check for divisors starting with 2 until the modulus result is 0 resulting in a false for being a prime number. Then the loop should increment to the next i value. The last part is an if statement that i had intended to add counters to the k variable that would keep track of the number of prime numbers.
boolean isPrime = true; int j = 2; int k = 1; for (int i = 17; i <= 53; i++){ { while (i % j == 0){ isPrime = false;
I am working on an assignment but I am not getting any out put and I couldn't fix it?The class HighLow below asks for three integers and prints the highest and lowest of them on screen. Your task is to write the missing methods high and low, which receives the integers user inputs as parameters and return the highest and lowest integers respectively.
import java.util.Scanner; public class HighLow { public static void main(String[] args) { int number1, number 2, number 3, high, low; Scanner reader = new Scanner(System.in);
