解析编译错误时到达文件末尾

我是一个java编程初学者。我做错了：在解析时到达文件结尾

I am a java programming beginner. What did i do to get the error: reached end of file while parsing

import java.util.Scanner;
class eng{
  public static void main(String[] args){
    Scanner input = new Scanner(System.in);
    String value; 
    String direct = "answer true or false to the following statement.";
    String ques = "Twelve is greater than seven";
    System.out.println(direct);
    System.out.println(ques);    
    value = input.nextLine();
    if ((value = "true")) {
      System.out.println("you are correct");
    } else {
       System.out.println("you are wrong my friend");              
    }
}
