I'm required to write a program that allows the user to enter up to 10 integer grades into an array. Stop the loop by typing in ‐1. Your main method should call an Average method that returns the average of the grades.I There's something wrong with my program , the count always stays 0 and the sum is always 1 less than the actual sum.Sample input and output :
Enter grade 1: 8
Enter grade 2: 9
Enter grade 3: 10
Enter grade 4: 5
Enter grade 5: 8
Enter grade 6: 9
Enter grade 7: -1
output
Average grade is 8.1666666667On line 13 I had count=count+1 ;

I'm trying to convert the first letter of every word in a String to uppercase. I've managed to isolate the first letter of every word and then make it uppercase but I don't know how to replace it.
public static StringBuffer makeUpperCase(){
String str = String.valueOf(input2);
for(int i = 0; i < str.length(); i++){
if(str.charAt(i) == ' '){
char var = str.charAt(i + 1);
var = Character.toUpperCase(var);
System.out.println(var);
}
}

public class Demo2
{
public static void main(String[] args)
{
String s1="hi how are you";
s1=s1.replace('a', 'A');
s1 =s1.replace('e', 'E');
s1 =s1.replace('i', 'I');

this is working properly.
but when i trying with Scanner i am facing problem.

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:
Java Code:
public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

If I use the class DecimalFormat to format long number, how can I convert it back to integer?
DecimalFormat longFormat = new DecimalFormat("#,###");
long testLong=11000;
String strLong=longFormat.format(testLong);
System.out.println("NUM : " + strLong);
//Assume that at this point I don't have
//testLong, I have only the strLong value...
long newLong=Long.parseLong(strLong) * 2;
//java.lang.NumberFormatException: For input string: "11,000

So I have to write a java program that converts hexadecimals to decimals without using the whole "integer.parseInt(AB1, 16)" method. I tried looking up how to do this but every forum/site I went to used this same method.

Write a Swing program that declares an empty array of grades with a maximum length of 50. Implement a JOptionPane input box within a while loop to allow the user to enter grades. When the user enters the sentinel value of -1, that will signal the end of the data input loop.
After the grades are entered, a content pane should display the grades sorted from lowest to highest. Write a loop that goes through the array looking for elements that are greater than zero (0). Keep a running count of those items, and also accumulate them into a grand total. Divide the grand total by the number of grades entered to find an average, and display the average at the end of the sorted list of grades. Use the DecimalFormat method to display the average to 2 decimal places.

I am using a static method to convert a string to an Integer object. Next using a instance method to convert Integer object to an int.
Compiler is giving me two "cannot find symbol" errors:
One pointing to the dot operator between "Integer.valueOf(s)"
The other pointing to the dot operator between "obj.intValue()"
I have latest JDK installed: jdk-7u51-windows-x64.exe
Looks like JCL installed correctly with rt.jar file located in "lib" directory under "Program Files"
Following is source code:
Java Code:
public class StringToInt
{
public static void main (String args [])
{
String s = "125";
Integer obj = Integer.valueOf(s);
int i = obj.intValue();
i += 10;
System.out.println(i);
}
} mh_sh_highlight_all('java');

I have a problem with functions connected to strings.
I have a random String, e.g. "Hello World!" and I have to change every capital Letter into a small letter and vise versa. This alone would be fairly simple, but I have to do it with two other strings.
lowercase= "abcde...z" and
uppercase="ABCDE...Z". Every small letter stands at the very same position as the capital letter, but in the other string.
There should be a letter for letter search in lowercase and uppercase for the letters of "Hello World".
How I could solve the task, however I need a way to search the first string, here "Hello World", according to position. A statement which does: "Give me the letter of position x". This found letter should be able to be stored in a variable or else be able to be used by another statement. And it should be compatible with a for lope.

Example : I have code and name but my code must start with the first letter of the inputed name if the 2 input is match it will be inserted into database
code = "A"001
name ="Angela"
= success this will inserted into database
else
code ="B"002
name="Angela"
=failed this will not inserted into database
else
code="A"003
name="Andy"
=success still accepts the input cause they have diff code number
What I am thinking on this was compare the code the name? if == it will be inserted but how do i get the 1st letter of the input name?

I am writing a program to convert a base 10 integer to any base 2-16. Here are the terms:"The method is to convert the decimal value the user selected into whatever base the user selected and print the converted value one place value at a time by using an index into an array of characters 0-9 amd A-F that is initialized to contain those characters.In the method you will find the largest place value (i.e. power of the base) that will divide into the decimal number.
Then you can set up a loop that will operate from that power down to and including the 0th power to determine how many times each place value goes into the decimal number. Using the loop counter, index into the character array to print the character that corresponds to the quotient number and then subtract the product of the place value and the quotient from the decimal number. With the power (loop index) decreased, repeat until you finish the 0th place value. Here's what I have so far:
import java.io.*;
import java.util.Scanner;
public class ConvertIt
{//start program
public static void main(String[] args)
{//start main
Scanner input = new Scanner(System.in);
System.out.println("Enter a positive integer from 0 to 10000.");
int number = input.nextInt();

So I have created this program but I am having a couple of small problems with it. The first problem is that the user inputted numbers should all be on the same line. I have spent hours trying to figure this out and I have looked online but I've had no luck. The second problem is that the "lowest score" should be 42 and not 42.0. I don't understand how to make it so the number is an integer. I have posted the output that i'm getting and the way the output should look like at the bottom.
import java.util.Scanner;
public class Random
{
public static void main(String [ ] args) {
Scanner input = new Scanner(System.in);
double a, b, c;
[Code] .....
This is the output that i'm getting.
Enter three scores: 87
42
94
The average is: 74.33333333333333
The lowest score was: 42.0
The average without the lowest score is: 90.5
The grade is: A
This is the way the output should look like.
Enter three scores: 87 42 94
The average is: 74.33333333333333
The lowest score was: 42
The average without the lowest score is: 90.5
The grade is: A

I've been asked to write a program that uses an array of grades, and to tally how many A's, B's etc ... The tallies are coming up incorrectly ... I'm putting the instructions at the end of this post to show what I should be getting.
import javax.swing.JOptionPane;
public class GradeCalculation {
public static void main(String[] args) {
//define array, grade values, and tally the amount of each grade
int grade[] = { 90, 100, 80, 85, 63, 73, 80, 92, 90};
int sum = 0;
int gradeA = 0;
int gradeB = 0;
[Code] ....
The assignment: Add logic inside the for loop to test if the number is between 90 and 100. If it is in this range, then add 1 to the tally of a gradeA. You should have another test to see if the number is between 80 and 89 and if it is it should add 1 to the tally of gradeB. You should continue to have tests for 70 to79 being gradeC; 60-69 being graded; and below 60 as being gradeF. After the for loop is done, you should display a list of how many students had A's, B's, etc. in the output message box.
Then the message box should display something like this:
The sum is 753
The average is 83
The largest test score is 100
The lowest test score is 63
The number of students with scores of 90-100 (A) is 4
The number of students with scores of 80-89 (B ) is 3
The number of students with scores of 70-79 (C ) is 1
The number of students with scores of 60-69 (D) is 1
The number of students with scores below 60 (F) is 0

where to create the array of chars that hold the letter grade. I am assuming that would be in the main with the other arrays. Passing it into an object creating a method in the record.java. Then displaying it in my main.
Take the Grades program and make a class. An object that hold 5 student names, an array of 5 chars that hold the letter grades, 5 arrays of four doubles each to hold the set of test scores. The class should have methods that return a specific student's name, average test score and a letter grade based on the average. Demonstrate the class in a program that allows the user to enter each student's name and their 4 tests scores. It should then display each student's average and letter grade.This is my main program:
import java.util.Scanner;
public class GradeBook{
public static void main(String[] args){
Scanner input = new Scanner(System.in);
Record[] students = {new Record(), new Record(), new Record(), new Record(), new Record()};
for(int j=0; j < 5; j++){
