For loop

[Code.Illusionist]

Attention: Noobish question.

So I was watching this tutorial here: http://www.tutorialspoint.com/java/java_loop_control.htm
and when I reached Enhanced for loop in Java , there is some problem. I do the same as they did but whenever I run application it seems there is error. Here is my code:

Code: (java) [Select]

public class Apples {
public static void main(String args[]) {
int [] numbers = {1,2,3,4};
for(int number : numbers) {
System.out.println(number);
}
}
}Does anyone have idea why this doesn't work?

[Kulverstukas]

System.out.println(); accepts a String as input, so just do System.out.println("" + number); to cast an int to a String.

I just tested it that way and still doesn't work. Btw, System.out.println can print integers because I can make application like this:

Code: (java) [Select]

public class Apples {
public static void main(String args[]) {
int [] numbers = {1,2,3,4};
for(int x = 0; x <4;x++) {
System.out.println(numbers[x]);
}
}
}

That's error I get. If that's what you asked for =)

Rightclick the project > Properties > Java Build Path > Libraries > which version of the jdk are you using in this project?
=> Make sure using jdk.1.7.0_51
Also  check properties > Java Compiler > which compiler compilance level did you choose?
=> Should be 1.7

System.out.println(); accepts a String as input, so just do System.out.println("" + number); to cast an int to a String.

See: http://docs.oracle.com/javase/7/docs/api/java/io/PrintStream.html#println%28int%29
The println method is overloaded with all possible types.

@Code.Illusionist
This is indeed a problem of the Java compiler version used. The error message tells clearly that you need 1.5 or greater. However, I don't get why this is below 1.5 to begin with. SE 1.5 is 10 years old.
The newest version is 1.8

Edit: And please stop watching thenewboston

I already set right version. I downloaded Java SE 8 and set everything right. But this virus probably disable all that again. Reinstalling system again.

Obviously you are not using the good version of Java. The error is pretty clear.

What exactly did you do?
Just downloading and installing a JDK is not enough. You need to change the settings in Eclipse.
Also: Eclipse ships with 1.7. There should be an option for a newer version already.

Actually there is no option for a newer version, until you install the plugin "Java 8 support for Eclipse Kepler SR2" in the Eclipse Marketplace

I was talking about Java 7. I meant "newer" compared to the version he was using before.

I see, makes sense now
