The canExecute() function is a part of File class in Java. This function determines whether the program can execute the specified file denoted by the abstract pathname. If the file path exists and the application is allowed to execute the file, this method will return true. Else it will return false.
Function signature:
public boolean canExecute()
Syntax:
file.canExecute();
Parameters: This function does not accept any parameter.
Return Value: This function returns a boolean value representing whether the specified file can be executed or not.
Exceptions: This method throws Security Exception if the read access to the file is denied
Below programs illustrates the use of canExecute() function:
Example 1: The file “F:\\program.txt” is an existing file in F: directory and the program is allowed the permission to execute the file.
import java.io.*;
public class solution {
public static void main(String args[])
{
File f = new File( "F:\\program.txt" );
if (f.canExecute()) {
System.out.println( "Executable" );
}
else {
System.out.println( "Non Executable" );
}
}
}
|
Output:
Executable
Example 2: The file “F:\\program1.txt” does not exist we will try to check if the file is executable or not.
import java.io.*;
public class solution {
public static void main(String args[])
{
File f = new File( "F:\\program1.txt" );
if (f.canExecute()) {
System.out.println( "Executable" );
}
else {
System.out.println( "Non Executable" );
}
}
