Write a Java Program to Create File and Write to the File
PROGRAM: Java Program to Create File and Write to the File
/*Java Program to Create File and Write to the File*/
1: Java Program to Create a File
// importing the File class
import java.io.File;
class Main {
public static void main(String[] args) {
// create a file object for the current location
File file = new File(“JavaFile.java”);
try {
// create a new file with name specified
// by the file object
boolean value = file.createNewFile();
if (value) {
System.out.println(“New Java File is created.”);
}
else {
System.out.println(“The file already exists.”);
}
}
catch(Exception e) {
e.getStackTrace();
}
}
}
2: Java Program to Write Content to the File
// importing the FileWriter class
import java.io.FileWriter;
class Main {
public static void main(String args[]) {
// creates a multiline string using + operator
// the string is a Java Program
String program = “class JavaFile { ” +
“public static void main(String[] args) { ” +
“System.out.println(\”This is file\”);”+
“}”+
“}”;
try {
// Creates a Writer using FileWriter
FileWriter output = new FileWriter(“JavaFile.java”);
// Writes the program to file
output.write(program);
System.out.println(“Data is written to the file.”);
// Closes the writer
output.close();
}
catch (Exception e) {
e.getStackTrace();
}
}
}
