for loops in java

[adebari olalekan]

can someone please help with this?

public class Forloops {
public static void main(String[] args) {
for(int i=0; i < 5; i++) {
System.out.printf("the value of i is: %d", i);
}
}
} 

i think the code is good but i keep getting this error:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method printf(String, Object[]) in the type PrintStream is not applicable for the arguments (String, int).

Such error occurs when you run a code when there is compile time error in your code and IDE shows that still you run that code then you get that error. Please check the red mark If there is any just hover mouse on the red mark to know what causing compile time error.
I ran your code successfully also got output, perhaps you named   .java file something else than Forloops, just check that...
Edit: Which IDE are you usig to run this program? What is compiler compliance level is set to ?
I think It needs at least 1.5 because printf was introduced in 1.5. printf() method.

I also compiled and executed this code without error.

If you're compiling from the command line, can you post the exact command?

jre

is 1.8 and the corresponding

jre

in eclipse is 1.7, so things got a confused,so i had to delete my eclipse and download the latest version for

jre1.8

I'm not sure but I think you just had to add JRE 8 to the installed JREs and set compiler compliance to 1.8 in windows --> preference. Did It work?

YES, it works perfectly, i later discovered that if the jre on eclipse is not in accordance with the one on the system, some methods will not work
