Reading File Content using FileReader Java

In this tutorial, I am sharing the simple program about Reading File Content using FileReader Java. The example program has been tested and output is shared in the same post.

FileReaderExample.java

package com.dineshkrish.files;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
public class FileReaderExample {
public static void main(String[] args) throws IOException {
// Defining the File Object for Input File to read
File inputFile = new File("abc.txt");
// Reader Object
FileReader fr = null;
try {
fr = new FileReader(inputFile);
// Reading the first Character
int data = fr.read();
// Reading each character until reach last character in file
while (data != -1) {
System.out.print((char) data); // will return integer
// value(ASCII) will be
// converted as character
data = fr.read();
}
} catch (FileNotFoundException ex) {
System.out.println(ex.getMessage());
ex.printStackTrace();
} catch (IOException ex) {
System.out.println(ex.getMessage());
ex.printStackTrace();
} finally {
// Closing the resources after the IO Operation
fr.close();
}
}
}
