从下面四段()代码中选择出正确的代码段()
A: abstractclassName{privateStringname;publicabstractbooleanisStupidName(Stringname){}}
B: publicclassSomething{voiddoSomething(){privateStrings="";intl=s.length();}}
C: publicclassSomething{publicstaticvoidmain(String[]args){Othero=newOther();newSomething().addOne(o);}publicvoidaddOne(finalOthero){o.i++;}}classOther{publicinti;}
D: publicclassSomething{publicintaddOne(finalintx){return++x;}}
A: abstractclassName{privateStringname;publicabstractbooleanisStupidName(Stringname){}}
B: publicclassSomething{voiddoSomething(){privateStrings="";intl=s.length();}}
C: publicclassSomething{publicstaticvoidmain(String[]args){Othero=newOther();newSomething().addOne(o);}publicvoidaddOne(finalOthero){o.i++;}}classOther{publicinti;}
D: publicclassSomething{publicintaddOne(finalintx){return++x;}}
举一反三
- 从下面四段代码中选择出正确的代码段() A: public class Something {public static void main(String[] args) {Other o = new Other();new Something().addOne(o);}public void addOne(final Other o) {o.i++;}}class Other {public int i;} B: public class Something {void doSomething () {private String s = ̶”;int l = s.length();}} C: abstract class Name {private String name;public abstract boolean isStupidName(String name) {}} D: public class Something {public int addOne(final int x) {return ++x; }}
- 从下面四段(A,B,C,D)代码中选择出正确的代码段 A: abstract class Name { private String name; public abstract boolean isStupidName(String name) {} } B: public class Something { void doSomething () { private String s = ""; int l = s.length(); } } C: public class Something { public static void main(String[] args) { Other o = new Other(); new Something().addOne(o); } public void addOne(final Other o) { o.i++; } } class Other { public int i; } D: public class Something { public int addOne(final int x) { return ++x; } }
- 从下面四段代码中选择出正确的代码段()
- 下面代码段的时间复杂度为()。{inti=0,s=0;while(i A: O(1) B: O(n) C: D:
- 以下代码运行输出是()classMan{ privateStringname=Jack; intage=30;}publicclassManTest{ publicStringtel; publicstaticvoidmain(String[]args){ Manm=newMan(); System.out.println(m.name); }}
