一直试图将我的房屋,房屋的年数和大小添加到GUI(更确切地说是JTextarea)中。最简单的方法是什么?尚未完全掌握数据输入。
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()); } } }
JTextArea有一个简单的append方法,应该可以轻松附加结果
JTextArea
append
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("\n"); } }
