In Java, you can use the FileWriter class, which allows you to write character data to a file. As an example, consider the following:
package week1.day2;
import java.io.FileWriter;
import java.io.IOException;
public class Calculator {
public static void main(String[] args) {
String textToWrite = "Monkey.D.Luffy";
try {
FileWriter writer = new FileWriter("C:\\Users\\arili\\git\\Assignments\\Selenium\\target\\OnePiece.txt");
writer.write(textToWrite);
writer.close();
System.out.println("Successfully wrote to file.");
} catch (IOException e) {
System.out.println("An error occurred while writing to file: " + e.getMessage());
e.printStackTrace();
}
}
}- In this example, we first create a String variable called textToWrite, which contains the text we want to write to the file.
- We then create a FileWriter object and pass the path of the file we want to write to as a parameter.
- Next, we call the write() method on the FileWriter object and pass our textToWrite string as a parameter.
- This writes the contents of the string to the file.
- Finally, we call the close() method on the FileWriter object to release any resources it may have been using and print a success message to the console.
- Note that the FileWriter class will create a new file with the given name if one does not already exist.
- If a file with a provided name already exists, its contents will be overwritten.
- If appending was needed over an existing file instead of overwriting it, you could pass true as a second parameter when creating the FileWriter object.
