标签：public finally stat closeable throws 语句 cep exception sed 当需要关闭资源时，通常会使用try-finally语句 java7新增了tryWithResource语句专门用于处理资源关闭的情况,基本结构为：try() 括号内用于初始化资源，资源需要实现java.lang.AutoCloseable接口，即实现close()方法。
括号内可以初始化多个资源，比如 tryWithResource语句类似Python中的with..as语句 Java TryWtihResource语句 标签：public finally stat closeable throws 语句 cep exception sed 原文地址：https://www.cnblogs.com/Peter2014/p/12848419.html public void test2() throws Exception {

} finally {

}
public class TryWith {
private class Resource implements AutoCloseable {
@Override
public void close() throws Exception {
System.out.println("resource is closed");
}
}
public void test() throws Exception {
try(Resource resource = new Resource()) {
System.out.println("doing something");
}

public static void main(String[] args) throws Exception {
TryWith tryWith = new TryWith();
tryWith.test();
}
