Java:代码重构/优化

请赐教:

你更倾向哪个？为什么？[可读性？内存关注？其他一些问题？]

1.

String strSomething1 = someObject.getSomeProperties1();
strSomething1 = doSomeValidation(strSomething1);
String strSomething2 = someObject.getSomeProperties2();
strSomething2 = doSomeValidation(strSomething2);
String strSomeResult = strSomething1 + strSomething2;
someObject.setSomeProperties(strSomeResult);

2.

someObject.setSomeProperties(doSomeValidation(someObject.getSomeProperties1()) + 
                             doSomeValidation(someObject.getSomeProperties2()));

如果你以其他方式做,那会是什么？你为什么这样做？

我会去:

String strSomething1 = someObject.getSomeProperties1();
String strSomething2 = someObject.getSomeProperties2();

// clean-up spaces
strSomething1 = removeTrailingSpaces(strSomething1);
strSomething2 = removeTrailingSpaces(strSomething2);

someObject.setSomeProperties(strSomething1 + strSomething2);

我个人的偏好是按行动组织,而不是按顺序组织.我认为它看起来更好.

我可能会介入:

String strSomething1 = doSomeValidation(someObject.getSomeProperties1());
String strSomething2 = doSomeValidation(someObject.getSomeProperties2());
someObject.setSomeProperties(strSomething1 + strSomething2);

选项#2在一行中似乎要做很多事情.它是可读的,但需要花费一点力气才能解析.在选项#1中,每一行都是非常易读且清晰的,但是当我复习时,冗长会减慢我的速度.我试图平衡上面的简洁和清晰,每行代表一个简单的代码"句子".

我更喜欢第二个.您可以通过一些格式化使其具有可读性,而无需声明额外的中间引用.

someObject.setSomeProperties(
    doSomeValidation( someObject.getSomeProperties1() ) + 
    doSomeValidation( someObject.getSomeProperties2() ));

您的方法名称提供了所需的所有解释.
