Java中如何将列表转数组呢?

列表转数组的实现思路

列表转数组可使用:
   list.toArray方法
   如:
   TestClass[] array = list.toArray(new TestClass[0]);
   或
   TestClass[] array = new TestClass[list.size()];
   list.toArray(array); // fill the array

package com.java265.other;

import java.util.ArrayList;
import java.util.List;

public class TestIKe {

	/**
	 * Java265.com List转数组的示例
	 */
	public static void main(String[] args) {
		List<TestClassEx> list = new ArrayList<TestClassEx>();

		list.add(new TestClassEx(1, "java265.com"));
		list.add(new TestClassEx(2, "java爱好者"));
		list.add(new TestClassEx(3, "java是我的最爱"));
		
		TestClassEx[] arrs = list.toArray(new TestClassEx[0]);

		for (int i = 0; i < arrs.length; i++) {
			System.out.println(arrs[i]);
		}
	}


}


class TestClassEx {

	private Integer id;
	private String name;

	public TestClassEx(Integer id, String name) {
		super();
		this.id = id;
		this.name = name;
	}

	@Override
	public String toString() {
		return "TestClassEx [id=" + id + ", name=" + name + "]";
	}

}
