寫在textarea的GUI答案我有一些問題就早了哪些這裏 解決了，但現在我的問題是，我得把這個代碼，並得到 出來的結果在GUI textarea的這個基本代碼。到目前爲止所做的一切是，第一個 設計了一個textArea和一個按鈕，但現在我卡住了。我不知道如何 將我用作基礎的代碼翻譯成GUI，並使其可能 單擊該按鈕並將答案顯示在文本顯示中。我 不知道我應該複製這個基地代碼或我需要做 在GUI內完全不同的東西？例如根據 jButtonActionPerformed，我需要做什麼...即時對不起，即時通訊新的 這個，所以失去了。我一整天都在搜索，但很難理解。如何從基本代碼
這是基礎代碼：
import java.lang.String;
class Vara {
//Deklarerar variabler
private String name;
private double price;
private int antal;
//tildela konstruktorer för de deklarerade variablerna
public Vara (String name, int antal, double price) {
this.name = name;
this.antal = antal;
this.price = price;
} // slut constructor
public void setName(String name) {
this.name = name; }
public void setPrice (double price) {
this.price = price; }
public void setAntal (int antal) {
this.antal = antal; }
public String getName() {
return this.name;}
public double getPrice() {
return this.price; }
public int getAntal() {
return this.antal; }
}
//testklassen ska stå som en egen klass
class Test {
public static void main(String[] args){
Vara var = new Vara("Banan",5, 12.5);
System.out.println("Namnet är " +var.getName() +" och priset är " +var.getPrice() +" och antalet är "+var.getAntal());// här slutar system.out
}
}
這裏是我的GUI代碼，我還沒有做任何事情迄今除了創造一個文本區域和一個按鈕開始。
