In this article, you'll learn how to **check if a file is readable, writable or executable** in Java.

## Using `Files.isReadable()` Method

In Java 7 or higher, you can use `Files.isReadable()` method to determine whether is a file is readable or not as shown below:

```java
if (Files.isReadable(Paths.get("input.txt"))) {
    System.out.println("File is readable.");
} else {
    System.out.println("File is not readable.");
}
```

## Using `Files.isWritable()` Method

Using `Files.isWritable()` static method from Java NIO API, you can check if a file is writable in Java:

```java
if (Files.isWritable(Paths.get("input.txt"))) {
    System.out.println("File is writable.");
} else {
    System.out.println("File is not writable.");
}
```

## Using `Files.isExecutable()` Method 

Java NIO API also provides `Files.isExecutable()` static method to determine whether a file is executable or not in Java:

```java
if (Files.isExecutable(Paths.get("input.txt"))) {
    System.out.println("File is executable.");
} else {
    System.out.println("File is not executable.");
}
```
