Hi;

I set the language level as follows in the shot. The thing is that I saw the red error sign but it's not clickable.

In my code, I have a line that requires Java7 as follows:

	try(FileInputStream fis = new FileInputStream(file); CheckedInputStream cis = new CheckedInputStream(fis, crc);){								
				sizeOfFile = file.length();

				byte[] buffer = new byte[4096];
				while(cis.read(buffer)>=0)
				{
					checksum = cis.getChecksum().getValue();				
				}
				System.out.println("The checksum of the file" + file + " is: " + checksum); 
				System.out.println("The file size is: " + sizeOfFile + " bytes");
			}
		}
		catch(IOException e){
			System.out.println("IO Exception thrown");
			e.printStackTrace();
			System.exit(1);
		}

Select allOpen in new window

What should I set the language for this?

Regards.

funny thing is that as said it's working in eclipse without an issue but when it comes to command line:

C:\Workdir\Crypto\CRCPro\src\com\baran\crc>javac -version
javac 1.7.0_21

C:\Workdir\Crypto\CRCPro\src\com\baran\crc>javac -source 1.7.0_21 target 1.7.0_2
1 *.java
javac: invalid source release: 1.7.0_21
Usage: javac <options> <source files>
use -help for a list of possible options

Select allOpen in new window

My environmental variables as system variable in windows is as follows:
JAVA_HOME C:\Program Files\Java\jdk1.7.0_21\bin

javac is only interested in major versions - 1.5,1.6, 1.7 etc
And actually you need to set neither source nor target in your case (since you're using 1.7)

Ok, I solved this. The problem is the language level in project settings, intellij. I had chosen level 8 since the expression above requires Java 1.7 but there is no level 8 and it fails. I take it to level 7 and voila.

Regards.

i simply had omitted the suggestion..He said this hours ago...Sorry.
