If Else - How To Not Execute Both Statements
Oct 4, 2014I am making a program, where the user answers 3 questions and then I add the number of correct answers in to the (int) numberofcorrect variable, then I want to print the results, and no matter how many correct, the program executes first the correct if statement, then the else statement.
Eg: I have 2 correct it will print:
"Grade B, 2 of 3 "
"You failed the test"
Why does it do that? How can I change my code so the else statement dosent print if one of the if statments is allready printed?I want to know how to not execute the else statement, if one of the if statements have allready been executed.Below is my current code for this problem:
if (numberofcorrect == 3){
System.out.println("Grade A, full score");}
if (numberofcorrect == 2){
System.out.println("Grade B, 2 of 3 ");}
if (numberofcorrect ==1) {
System.out.println("Grade C, 1 of 3");}
else {
System.out.println("You failed the test"); }

Compiles But Won't Execute - JCreator
Oct 18, 2014I was typing up this program and when I compile it, there aren't any errors, but it won't advance past the second conditional.
Here's the code:

How Compiler Picks What Method To Execute
Feb 20, 2014public class Main {
private static void foo(Integer a) {
System.out.println("Integer");
}
private static void foo(long a) {
System.out.println("long");
[Code] ....
This code prints long. Why is that? How did compiler decided that it likes long version of foo() method the most. If I had to guess I'd pick int... or possibly Integer as they are most similiar to what was passed. But why long?

Jar Should Be Present To Execute Main Class
Mar 18, 2014I have few queries regarding compiling v/s execution of a java program. Suppose I have a Main Class which is referring to class Test which is present in JarA. Now, at compile time, this jar JarA must be present in classpath/buildpath. So, what actually is the action performed by the compiler by referring to this jar?
Now, at runtime also, this jar should be present to execute the Main class. Is this correct? If yes, then what is the action performed by JRE when it refers to this class at runtime? WOn't all the dependencies be resolved at compile time only?

Nested If Statement - Execute If True
Feb 16, 2015I have a problem with an if statement I've done. I'm not sure how to fix my problem. I'll post the code of the if statement and the output.
if (box = true &&(shippingSwitch ==1))
{
if (ounces < .5)
{
additionalPrice = ((ounces % .5)/(0.0625))*1.25;
shippingPrice = 15.75 + additionalPrice;//((weight / 8)+ (weight % 8));
[Code] ....
Here's the output I get using println to test it.
Please enter 1 if your package is a letter and 2 if your package is a box
2
Please enter weight in pounds (Example: 1.2):
1.2
Please enter your shipping service option:
Press 1 for Next Day Priority:
Press 2 for Next Day Standard:
Press 3 for Two Day Shipping:
1
7.00
If I comment out the else statement on the last line of code I get the following output:
Please enter 1 if your package is a letter and 2 if your package is a box
2
Please enter weight in pounds (Example: 1.2):
1.2
Please enter your shipping service option:
Press 1 for Next Day Priority:
Press 2 for Next Day Standard:
Press 3 for Two Day Shipping:
1
13.75
What I want to happen is the code under the first comment to to execute if true, or go to the code under the next comments and execute if that statement is true and if that is not true I want the last block of code to execute underneath the last comments.
