一直在尝试将我的数组、房子的年份和大小添加到 GUI 中，更准确地说是 JTextarea.这样做的最简单方法是什么?还没有完全掌握数据输入.

Been trying to add my array, year and size of a house into a GUI, more precisely JTextarea. What's the simplest way of doing so? Not quite grasped data input yet.

public class House { private int year; private int size; private static int nbrOfHouses; public static final int MIN_SIZE = 10; public House(int year, int size) { this.year = year; this.size = size; } public static int getNbrHouses() { return nbrOfHouses; } public int getYear() { return year; } public int getSize() { return size; } } House[] myHouse = new House[10];{ myHouse[0] = new House(1902, 120); myHouse[1] = new House(1954, 180); myHouse[2] = new House(1995,90); for(int i=0; i< myHouse.length; i++){ if(myHouse[i]!=null){ System.out.println(myHouse[i].getSize()); } } }

推荐答案

JTextArea 有一个简单的 append 方法应该可以轻松附加结果

JTextArea has a simple append method that should make it easy to append the results

例如...

for(int i=0; i< myHouse.length; i++){ if(myHouse[i]!=null){ textArea.append("Year: "); textArea.append(Integer.toString(myHouse[i].getYear())); textArea.append(". Size: "); textArea.append(Integer.toString(myHouse[i].getSize())); textArea.append(" "); } }
