Apache容器扩展Transformer类

public static void main(String[] args) {

// 转换规则
Transformer<Long, String> trans = new Transformer<Long, String>() {
@Override
public String transform(Long input) {
return new SimpleDateFormat("yyyy-MM-dd hh-mm-ss")
.format(input);
}
};

// 容器
Set<Long> set = new HashSet<Long>();
set.add(123456789L);
set.add(1234323232323L);
set.add(32453253453245L);
// 开始转换
Collection<String> result = CollectionUtils.collect(set, trans);
// 遍历容器

Iterator<String> iter = result.iterator();
while (iter.hasNext()) {
System.out.println(iter.next());
}

}
}
