怎么样把一个数组写到一个jTable中啊

[luruifang]

我要做的是要把一个数组写到jTable中,怎么写啊

[myidd00701]

JTable aaa=new JTable(object[][] obj1,object[] obj2);

上面的obj2是JTable的列名，obj1是JTable的数据，这是表格生成时候赋值的，如果想动态写入的话，如下代码：


JTable table =new JTable(1,4); //生成个1行4列的表格
DefaultTableModel dtm=(DefaultTableModel)table.getModel();//获取表格的DefaultTableModel对象
Object[] rowData=("xxx","xxx","xxx","xxx");//存放数据的数组
dtm.addRow(rowDate);//插入行
dtm.removeRow(3);//删除行


小tips：JTable 的外观是通过一个模型来控制的，这是一种MVC模式，要改变JTable的外观，就必须获得其模型才可以～

先要生成他的JTableModel
写一个Model类implements abstractJTableModel 实现他的3个方法

例如我写一个学生类，这个类有4个属性；
//Student.java
class Student{
	private String name;
	private String gender;
	private int age;
	private int score;
	public Student(String name, String gender, int age, int score) {
		super();
		this.name = name;
		this.gender = gender;
		this.age = age;
		this.score = score;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getGender() {
		return gender;
	}
	public void setGender(String gender) {
		this.gender = gender;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public int getScore() {
		return score;
	}
	public void setScore(int score) {
		this.score = score;
	}
}

//TableModelForArray.java 写一个JTableModel类
class TableModelForArray extends AbstractTableModel{
	private Student[] arr;
	
	public TableModelForArrayList(Student[] arr){
		this.arr=arr;
	}
	@Override
	public String getColumnName(int index) {
		switch(index){
		case 0:return "姓名";
		case 1:return "性别";
		case 2:return "年龄";
		case 3:return "成绩";
		default:return null;
		}
	}

	public int getColumnCount() {
		return 4;
	}

	public int getRowCount() {
		return arr.length;
	}

	public Object getValueAt(int row, int col) {
		Student s= arr[row];
		switch(col){
		case 0:return s.getName();
		case 1:return s.getGender();
		case 2:return s.getAge();
		case 3:return s.getScore();
		}
		return null;
	}
}

//生成JTable
Student[] stus = {.................};
JTable table =new JTable(new TableModelForArray(stus));
