The exists() function is a part of the File class in Java. This function determines whether the is a file or directory denoted by the abstract filename exists or not. The function returns true if the abstract file path exists or else returns false.
Syntax:
public boolean exists()
file.exists()
Parameters: This method does not accept any parameter.
Return Value: The function returns the boolean value if the file denoted by the abstract filename exists or not.
Exception: This method throws Security Exception if the write access to the file is denied
Implementation: Consider file on the local directory on a system where local directory be as below provided.
“F:\\program.txt”
Example 1:
Java
import java.io.*;
public class GFG {
public static void main(String args[])
{
File f = new File( "F:\\program.txt" );
if (f.exists())
System.out.println( "Exists" );
else
System.out.println( "Does not Exists" );
}
}

Output:
Exists
Now let us consider the use-case where file is writable (“F:\\program1.txt”)
Example 2:
Java
import java.io.*;
public class GFG {
public static void main(String args[])
{
File f = new File( "F:\\program1.txt" );
if (f.exists())
System.out.println( "Exists" );
else
System.out.println( "Does not Exists" );
}
}
