public static Customer hasCustomer(String id,String pwd) { if ( ( id == null || id.length() < 1) &&
public static Customer hasCustomer(String id,String pwd)
{
if ( ( id == null || id.length() < 1) && (pwd == null || pwd .length() < 1))
{
return null;
}
.
如果if语句成立,下面的语句还会执行吗,下面不存在else语句,return null

不会执行,return 不仅仅有返回的意思还有跳出的意思 return null 意思是返回一个空值
并且跳出方法所以下面的代码不会在执行了

public static Customer hasCustomer(String id,String pwd) { i public class Test{ public static void main(String args[]){ i c# public static bool IsSelectNode(string xmlPath,string nod public static void main(String[] args) { public class Breaker { static String o = ""; public class SystemTest { public static void main(String[] a public class Foo { public static void main(String[] args) { public class Test { public static void main(String[] agrs) { public class TreeMapDemo { public static void main(String[] java 九九乘法表public class s99{public static void main(String[] public String removeType(String sou){ c#不懂得地方 private static string sandnamevalue;public static st
