Java FileReader Class ready() Method with Examples
Java FileReader class is used to read data from the data file. It returns the data in byte format as FileInputStream class. This is a character-oriented class that is used for file handling in Java.
ready() Method of FileReader Class
It checks if the file reader is ready to be read. It will return a boolean that states if the reader is to be ready. It basically checks whether this stream is ready to be read or not. An InputStreamReader is ready if its input buffer is not empty as, or Thus, bytes are available to be read from the under byte stream of it.
public void ready()
Exception Thrown: IOException
Now we will be going through the sleep() method of thread class parallelly in order to have a good understanding of the ready() method of FielReader class. FOr that do remember certain important key points as follows:
Java FileReader Class is a class that is basically a file of execution of the programs to read data from the data file. It is present in FileInputStream class. contains the Java FileReader Class ready() method. The ready() method is used to check if the file reader is ready to be read. It will return a boolean that states if the reader is to be ready for it
- Method Whenever FileReader Class ready() functions to execute, state if the reader is to be ready for it to read or not
- If any other error or action interrupts when the file is, then IOException will be thrown.
Overrides: ready() in class Reader
Return Type: sleep() Method
It does not return any value, i.e., the return type of the sleep function is void. This method returns True if the next read() is Explaining not to block for input, or false otherwise. hence Note – that returning false does not guarantee that the next read will be blocked.
Exception Thrown: IOException is thrown if an I/O error has occurred.
