如何使用NetBeans在Java中将主类链接到jframe表单
[英]how to link a main class to a jframe form in java using netbeans
问题描述
美好的一天！
我使用Netbeans创建了一个代码，它可以很好地执行进程。 现在，我希望给定输入并通过用户界面显示输出。 然后，我创建了2个Jframe，其中1个用于收集用户的输入，另一个创建由代码执行后显示结果。
但是，我无法将接口链接到主类（称为NgramBetaE），因为我不知道该怎么做。
我非常欢迎您提出建议。
整个主要类别是：
package ngrambetae;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.*;
/**

public class NgramBetaE {
static LinkedList<String> allWords = new LinkedList<String>();
static LinkedList<String> distinctWords = new LinkedList<String>();
static String[] hashmapWord = null;
static int wordCount;
public static HashMap<String,HashMap<String, Integer>> hashmap = new HashMap<>();
public static HashMap<String,HashMap<String, Integer>> bigramMap = new HashMap<>();
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
//prompt user input
Scanner input = new Scanner(System.in);
//read words from collected corpus; a number of .txt files
File directory = new File("Corpus");
File[] listOfFiles = directory.listFiles();//To read from all listed iles in the "directory"
int lineNumber = 0;
String line;
String files;
String delimiters = "[()?!:;,.\\s]+";
//reading from a list of text files
for (File file : listOfFiles) {
if (file.isFile()) {
files = file.getName();
try {
if (files.endsWith(".txt") || files.endsWith(".TXT")) { //ensures a file being read is a text file
BufferedReader br = new BufferedReader(new FileReader(file));
while ((line = br.readLine()) != null) {
line = line.toLowerCase();
hashmapWord = line.split(delimiters);
//CALCULATING UNIGRAMS
for(int s = 0; s < hashmapWord.length; s++){
String read = hashmapWord[s];
allWords.add(read);
//count the total number of words in all the text files combined
//TEST
wordCount = 0;
for (int i = 0; i < allWords.size(); i++){
wordCount ++;
}
}
//CALCULATING BIGRAM FREQUENCIES
for(int s = 0; s < hashmapWord.length -1; s++){
String read = hashmapWord[s];
final String read1 = hashmapWord[s + 1];
HashMap<String, Integer> counter = bigramMap.get(read);
if (null == counter) {
counter = new HashMap<String, Integer>();
bigramMap.put(read, counter);
}
Integer count = counter.get(read1);
counter.put(read1, count == null ? 1 : count + 1);
}
//CALCULATING TRIGRAM FREQUENCIES
for(int s = 0; s < hashmapWord.length - 2; s++){
String read = hashmapWord[s];
String read1 = hashmapWord[s + 1];

String readTrigrams = read + " " + read1;
HashMap<String, Integer> counter = hashmap.get(readTrigrams);
if (null == counter) {
counter = new HashMap<String, Integer>();
hashmap.put(readTrigrams, counter);
}
Integer count = counter.get(read2);
counter.put(read2, count == null ? 1 : count + 1);
}
}
br.close();
}
} catch (NullPointerException | IOException e) {
e.printStackTrace();
System.out.println("Unable to read files: " + e);
}
}
}
//COMPUTING THE TOTAL NUMBER OF WORDS FROM ALL THE TEXT FILES COMBINED
System.out.println("THE TOTAL NUMBER OF WORDS IN COLLECTED CORPUS IS : \t" + wordCount + "\n");
for(int i = 0, size = allWords.size(); i < size; i++){
String distinctWord = allWords.get(i);
//adding a word into the 'distinctWords' list if it doesn't already occur
if(!distinctWords.contains(distinctWord)){
distinctWords.add(distinctWord);
}
}
//PRINTING THE DISTINCT WORDS
System.out.println("THE DISTINCT WORDS IN TOTAL ARE :\t " + distinctWords.size() + "\n");
System.out.println("PRINTING CONTENTS OF THE BIGRAMS HASHMAP... ");
System.out.println(bigramMap);

//QUITTING APPLICATION
String userInput = null;
while(true) {
System.out.println("\n**********************************************************************************************************************************************************************************************************************************");
System.out.println("\n\n\t\tPLEASE ENTER A WORD OR PHRASE YOU WOULD LIKE A PREDICTION OF THE NEXT WORD FROM:");
System.out.println("\t\t\t\t(OR TYPE IN 'Q' OR 'q' TO QUIT)");
userInput = input.nextLine();
if (userInput.equalsIgnoreCase("Q")) break;
//FORMAT USER INPUT
String[] users = userInput.toLowerCase().split("[?!,.\\s]+");
if (users.length < 2) {
userInput = users[0];
//System.out.println("\nENTRY '" + userInput + "' IS TOO SHORT TO PREDICT NEXT WORD. PLEASE ENTER 2 OR MORE WORDS");
//CALCULATING BIGRAM PROBABILITY
int sum = 0;
try {
for(String s : bigramMap.get(userInput).keySet()) {
sum += bigramMap.get(userInput).get(s);
}
String stringHolder = null;
double numHolder = 0.0;
for(String s : bigramMap.get(userInput).keySet()) {
//System.out.println("TWO");
double x = Math.round(bigramMap.get(userInput).put(s, bigramMap.get(userInput).get(s))/ (double)sum *100 );
if(s != null){
if(numHolder < x ){
stringHolder = s;
numHolder = x;
}
}
}
System.out.println("\nNEXT WORD PREDICTED IS '" + stringHolder + "'");
System.out.println("ITS PROBABILITY OF OCCURRENCE IS " + numHolder + "%");
} catch (Exception NullPointerException) {
System.out.println("\nSORRY. MATCH NOT FOUND.");
}
} else {
userInput = users[users.length - 2] + " " + users[users.length - 1];
// System.out.println("FROM USER WE GET....");
// System.out.println(bigrams.get(userInput).keySet());
/* CALCULATING TRIGRAM PROBABILITY*/
int sum = 0;
try {
for(String s : hashmap.get(userInput).keySet()) {
sum += hashmap.get(userInput).get(s);
}
String stringHolder = null;
double numHolder = 0.0;
for(String s : hashmap.get(userInput).keySet()) {
//System.out.println("TWO");
double x = Math.round(hashmap.get(userInput).put(s, hashmap.get(userInput).get(s))/ (double)sum *100 );
if(s != null){
if(numHolder < x ){
stringHolder = s;
numHolder = x;
}
}
}
System.out.println("\nNEXT WORD PREDICTED IS '" + stringHolder + "'");
System.out.println("ITS PROBABILITY OF OCCURRENCE IS " + numHolder + "%");
} catch (Exception NullPointerException) {
System.out.println("\nSORRY. MATCH NOT FOUND.");
}
}
}
input.close();
}
}
我想在运行该项目时出现的第一个Jframe有一个文本框和一个按钮。
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String usersInput = jTextField1.getText();
Interface1 s = new Interface1();
s.setVisible(true);
dispose();
}
我希望用户在文本框中输入数据，然后单击“预测下一个单词”按钮，然后代码执行的输出将显示在第二个jframe上，它具有3个标签和相对文本区域。
注意; 我无法粘贴屏幕截图，但是如果您运行NgramBetaE类，您将对接口的外观有所了解，因为我试图对其进行解释。
谢谢

甚至不要尝试将您的GUI代码链接到您的NgramBetaE代码，因为您需要做更多的工作，因为NgramBetaE仅仅是一种巨大的静态主方法，该方法通过扫描仪从控制台获取用户输入，并通过printlns。 融合这两个就像试图将一个方形的钉子插入一个圆孔。
而是着眼于面向对象的编码来重写整个过程，包括创建具有实例字段和方法的，与OOP兼容的模型类，以及用于获取输入并显示它的单个GUI，其中包含模型的实例类，并在此实例上调用实例方法。
考虑为以下项目创建非GUI类和方法：
- 从文本文件中读取数据
- 分析和散列文本文件中包含的数据，包括计算单词频率等...
- 分析后以任何可能的数据形式返回所需的数据。
- 一种允许输入字符串/短语进行测试并返回其预测概率的方法
然后为以下内容创建GUI代码：
- 从用户获取选定的文本文件。 JFileChooser和支持的代码在这里效果很好。
- 按钮开始分析
- JTextField允许输入短语
- JTextArea或JTable可以显示分析结果
请注意，您应该避免在GUI中使用多个JFrame。 有关更多信息，请查看“使用多个JFrame，良好/不良实践？”。
