Given in a single JSP page: <%@ taglib prefix=’java’ uri=’myTags’ %> <%@ taglib prefix=’JAVA’ uri=’moreTags’ %> Which two are true?()
int index = 1; int [] foo = new int [3]; int bar = foo [index]; int baz = bar + index; What is the result?()
String foo = “blue”; Boolean[]bar = new Boolean [1]; if (bar[0]) { foo = “green”; } What is the result? ()
Given: 1.<% int[] nums = {42,420,4200}; 2.request.setAttribute("foo", nums); %> 3.${5 + 3 lt 6} 4.${requestScope[’foo’][0] ne 10 div 0} 5. ${10 div 0} What is the result?()
Given the fully-qualified class names: com.foo.bar.Dog com.foo.bar.blatz.Book com.bar.Car com.bar.blatz.Sun Which graph represents the correct directory structure for a JAR file from which those classes can be used by the compiler and JYM?()
3. string foo = “ABCDE”; 4. foo.substring(3); 5. foo.concat(“XYZ”); 6. Type the value of foo at line 6.()
public class Test { public static void main (String args) { string foo = “blue”; string bar = foo; foo = “green”; System.out.printIn(bar); } } What is the result?()
Given: 6.<% int[] nums = {42, 420, 4200}; 7.request.setAttribute("foo", nums); %> Which two successfully translate and result in a value of true?()
Which code determines the int value foo closest to a double value bar?()
3. string foo = “ABCDE”; 4. foo.substring(3); 5. foo.concat(“XYZ”); 6. Type the value of foo at line 6.()
int index = 1; int foo = new int ; int bar = foo [index]; int baz = bar + index; What is the result?()
String foo = “blue”; Booleanbar = new Boolean [1]; if (bar[0]) { foo = “green”; } What is the result?()
Which statements concerning the relationships between the following classes are true?() class Foo { int num; Baz comp = new Baz(); } class Bar { boolean flag; } class Baz extends Foo { Bar thing = new Bar(); double limit; }
public class Test { public static void main (String [] args) { string foo = “blue”; string bar = foo; foo = “green”; System.out.printIn(bar); } } What is the result?()
Given: 1. public interface Foo { 2. int k = 4: 3. } Which three are equivalent to line 2?()
Given 1. public class Foo { 2. public static void main (String [] args) } 3. try { return;} 4. finally { Syste.out.printIn (“Finally”);} 5. } 6. } What is the result()?
读代码:public class Test {public static void main (String [] args) {String foo = “blue”;String bar = foo;foo = “green”;System.out.println(bar);}}结果是:
Given:1.<%int[]nums={42,420,4200};2.request.setAttribute("foo",nums);%>3.${5+3lt6}4.${requestScope[’foo’][0]ne10div0}5.${10div0}Whatistheresult?()

Given:6.<myTag:foobar=’42’>7.<%="processing"%>8.</myTag:foo>andacustomtaghandlerforfoowhichextendsTagSupport.Whichtwoaretrueaboutthetaghandlerreferencedbyfoo?()
以下代码的运行结果是function foo(){console.log(bar) // 结果let bar = 1;}foo
以下代码中的输出结果是var foo = bar0;var bar = 1;console.log(foo)()
有如下类声明:clasFooinbar;;则Foo类的成员bar是()
