Is it me or just Eclipse... JEdit too...

[Gjorgi Var]

Hola,
I have recently downloaded Eclipse 3.0.2 and happily rushed to try it out on a simple app from a Java book. In an attempt to run that app in Eclipse it reported several synthax errors, but when I tried to compile the same app "manually" (source code in Notepad, javac command on the command prompt etc.) none of those errors were reported and the app executed just as expected. No changes were made in the source code while attempting to compile from the command prompt. How can that be, a synthax error in Eclipse is not a synthax error out of it?!
JEdit is a story too... compiler plug-in is reported to be missing when attempting to compile, although Plug-in Manager lists it as present and I am sure that it was downloaded... am I doing something wrong?

Gjorgi,
Can you post the error that you are getting? That will help us give a more specific answer.

In general, Eclipse allows you to customize whether certain things are treated as warnings, errors or ignored. For example, you can have Eclipse warn you about unused code. It is possible these settings are what is triggering your error. It could also be a classpath issue.

And here it is:

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
Syntax error on token ",", invalid AssignmentOperator
Syntax error on token ",", invalid AssignmentOperator
Syntax error on token ",", invalid AssignmentOperator
Syntax error on token(s), misplaced construct(s)
Syntax error on token ")", invalid AssignmentOperator
 
at EmployeeSort.main(EmployeeSort.java:20)

It basically objects to use of commas during array initialization (although I don't understand why is the last objection on ")").
The same untouched code that raised the exception was not at all objectionable during command-line compilation...

Well, let's see the code. Tell us which is line 20.

[Gjorgi Var]

import java.util.*;
public class EmployeeSortTest {
 
public static void main(String[] args) {
Employee[] staff = new Employee [3];
staff[0]= new Employee("Harry Hacker", 35000);
staff[1]= new Employee("Carl Cracker", 75000);
staff[2]= new Employee("Tony Tester", 100000);

Arrays.sort(staff);
//print out information about all Employee objects

for(Employee e : staff)
System.out.println("name= "+ e.getName()+"salary= "+e.getSalary());
}
}
 
class Employee implements Comparable<Employee>{
public Employee (String n, double s){name=n; salary=s;}
public String getName(){return name;}
public double getSalary(){return salary;}
public void raiseSalary(double byPercent){
double raise=salary*byPercent/100;
salary +=raise;
}
 
 public int compareTo(Employee other){
 if(salary < other.salary)return -1;
 if (salary > other.salary) return 1;
 return 0;
 }
private String name;
private double salary;
}

And there it is...

Eclipse 3.0 doesn't recognise the 1.5 language constructs you're using and reports them as syntax errors.

[Ilja Preuss]

Jeroen is right. I you want to use Java 5, you need to install the latest Eclipse 3.1 milestone.
