Java基础CleanCode之lombok&try-with-resources

Lombok之@Data、@Accessors

package com.base;

import lombok.Data;
import lombok.experimental.Accessors;

// @Data等价于@ToString、@EqualsAndHashCode、@Getter、@Setter和@RequiredArgsConstructor的集合
@Data
// 为属性setter提供链式操作功能
@Accessors(fluent = true)
public class TestLombok
{

    private long id;
    
    private String value;
    
    public static void main(String[] args)
    {
        TestLombok testLombok = new TestLombok().id(111111).value("111111");
        System.out.println(testLombok.toString());
    }

}

使用try-with-resources安全简洁关闭资源

try (FileInputStream ins = new FileInputStream(file)) {
    int n;
    while ((n = ins.read()) != -1) {
        // ...
    }
}

替代传统写法：

FileInputStream ins = new FileInputStream(file);
try {
    int n;
    while ((n = ins.read()) != -1) {
        // ...
    }
} finally {
    ins.close();
}
