A: ${foo.advice}
B: ${request.foo.advice}
C: ${requestScope.foo.advice}
D: ${requestScope[foo[advice]]}
E: ${requestScope["foo"]["advice"]}
举一反三
- Which two methods， inserted individually， correctly complete the Three class？（） A: public void foo（）{ } B: public int foo（）{return 3；} C: public Two foo（）{return this；} D: public One foo（）{return this；} E: public Object foo（）{return this；}
- 下面哪个程序是语法正确的？ A: foo::IO() foo=do line=getLine printline B: foo::IO() foo=do letline=getLine printline C: foo::IO() foo=do letline-getLine printline D: foo::IO() foo=do line-getLine printline
- 读代码: public class Test { public static void main (String args[]) { class Foo { public int i = 3; } Object o = (Object) new Foo(); Foo foo = (Foo)o; System.out.println(foo.i); } } 结果是：
- Could you give me some( ) about how to deal with this problem? A: advice B: advise C: advisor
- 下面哪个程序是语法正确的？ A: foo::IO() foo=do line-getLine n=readline::Int printn B: foo::IO() foo=do line-getLine n-readline::Int printn C: foo::IO() foo=do line-getLine letn=readline::Int printn D: foo::IO() foo=do letline=getLine letn=readline::Int printn
