Files isExecutable() method in Java with Examples
Last Updated :

isExecutable() method of java.nio.file.Files help us to check whether a file is executable. This method checks that a file exists on this path or not and if it exists then Java virtual machine has appropriate privileges to execute the file or not. The semantics may differ when checking access to a directory.
For example, on UNIX systems, checking for execute access checks that the Java virtual machine has permission to search the directory in order to access file or subdirectories. So we can say that isExecutable() method returns true if the file exists and is executable, or it would return false if the following cases:
Syntax:
public static boolean isExecutable(Path path)
Parameters: This method accepts a parameter path which is the path to the file to check.
Return value: This method returns true if the file exists and is executable, or it would return false if the following cases:
Exception: This method will throw SecurityException in the case of the default provider, and a security manager is installed, the checkExec is invoked to check execute access to the file.

Below programs illustrate isExecutable(Path) method:
Program 1:
import java.io.IOException;
import java.nio.file.*;
public class GFG {
public static void main(String[] args)
{
Path path
= Paths.get(
"D:\\GIT_EWS_PROJECTS\\logger"
+ "\\src\\logger"
+ "\\GFG.java" );
boolean result
= Files.isExecutable(path);
System.out.println( "File " + path
+ " is Executable = "
+ result);
}
}

Output:
Program 2:
import java.io.IOException;
import java.nio.file.*;
public class GFG {
public static void main(String[] args)
{
Path path
= Paths.get(
"D:\\User Aman\\Documents"
+ "\\MobaXterm\\home"
+ "\\.ssh\\hostkeys\\file1.txt" );
boolean result
= Files.isExecutable(path);
System.out.println( "File " + path
+ " is Executable = "
+ result);
}
}
