Currently I'm learning how to read from .txt files, and to print them out to a .txt file. I'm still pretty new to java coding. So with my assignment I'm supposed to read in from a file that was provided by the professor, and write out to an outFile.txt. I cannot get anything to print in the outFile.txt. It keeps coming blank. I can't figure out what I did wrong. Can someone help please? I've got 5 classes, plus the driver class, and a text file. Thank you. Driver.java--

package project3;

import java.io.*;

import java.util.*;

import java.util.Scanner;

public class Driver {

public static void main(String[] args) throws IOException {

// TODO Auto-generated method stub

PrintWriter outFile = new PrintWriter(new FileWriter("outFile.txt"));

Scanner inFile = new Scanner(new FileReader("inFile.txt"));

while (inFile.hasNext()) {

String shapeType = inFile.next();

if (shapeType == "Rectangle") {

int rectLength = inFile.nextInt();

int rectWidth = inFile.nextInt();

Rectangle rectangle1 = new Rectangle(rectLength, rectWidth);

Rectangle.getrectArea();

Rectangle.getrectPerimiter();

outFile.println(rectangle1);

} // end of if

else if (shapeType == "SquAre") {

int sqSide = inFile.nextInt();

Square square1 = new Square(sqSide);

Square.getSqrArea();

Square.getSqrPerimeter();

outFile.println(square1);

}

else if (shapeType == "Circle") {

double circleRadius = inFile.nextInt();

double circleCircumference = inFile.nextInt();

Circle circle1 = new Circle(circleRadius, circleCircumference);

Circle.area();

Circle.circumference();

outFile.println(circle1);

}

else if (shapeType == "Triangle") {

int triBase = inFile.nextInt();

int triHeight = inFile.nextInt();

Triangle triangle1 = new Triangle(triBase, triHeight);

Triangle.gettriArea();

Triangle.gettriPerimiter();

outFile.println(triangle1);

}

else if (shapeType == "ParallelograM") {

int paraBase = inFile.nextInt();

int paraHeight = inFile.nextInt();

Parallelogram para1 = new Parallelogram(paraBase, paraHeight);

Parallelogram.getparaArea();

Parallelogram.getparaPerimiter();

outFile.println(para1);

}

else if (shapeType == "Square") {

int sqSide = inFile.nextInt();

Square square2 = new Square(sqSide);

Square.getSqrArea();

outFile.println(square2);

}
