现有: class Foo { public static void main (String [] args) { int x=O; int y=4; for (int z=0; z<3; Z++; X++) { if(x>1&++y<10) y++; } System. out .println (y); } } 结果是什么?()
1.public class Test { 2.public static void main (String args[]) { 3.class Foo { 4.public int i = 3; 5.} 6.Object o = (Object) new Foo(); 7.Foo foo = (Foo)o; 8.System.out.printIn(foo. i); 9. } 10.} What is the result?()
int index = 1; String [] test = new String[3]; String foo = test[index]; What is the result?()
String foo = “blue”; Boolean[]bar = new Boolean [1]; if (bar[0]) { foo = “green”; } What is the result? ()
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?()
public class Delta { static boolean foo(char c) { System.out.print(c); return true; } public static void main( String[] argv ) { int i =0; for ( foo(‘A’); foo(‘B’)&&(i<2); foo(‘C’)){ i++ ; foo(‘D’); } } } What is the result?()
3. string foo = “ABCDE”; 4. foo.substring(3); 5. foo.concat(“XYZ”); 6. Type the value of foo at line 6.()
String foo = “blue”; Booleanbar = new Boolean [1]; if (bar[0]) { foo = “green”; } What is the result?()
2. public class Foo implements Runnable ( 3. public void run (Thread t) { 4. system.out.printIn(“Running.”); 5. } 6. public static void main (String[] args) { 7. new thread (new Foo()).start(); 8. ) 9. ) What is the result?()
public class test( public static void main(stringargs){ string foo = args [1]; string foo = args ; string foo = args ; } ) And command line invocation: Java Test red green blue What is the result? ()
下面这段代码中,变量myChar的结果是()。 Dim myString As String = "ABCDE" Dim myChar As Char myChar = myString.Chars(3)
5. String foo = “base”; 6. foo.substring(0,3); 7. foo.concat(“ket”) 8. Type the value of foo at line 8.()
int index = 1; String test = new String; String foo = test[index]; What is the result?()
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 class Foo { 2. public static void main (String [] args) } 3. try { return;} 4. finally { Syste.out.printIn (“Finally”);} 5. } 6. } What is the result()?
class Foo { public static void main(String [] args) { int x = 0; int y = 4; for(int z=0; z 〈 3; z++, x++) { if(x 〉 1 & ++y 〈 10) y++; } System.out.println(y); } } 结果是什么?()
public class test( public static void main(string[]args){ string foo = args [1]; string foo = args [2]; string foo = args [3]; } ) And command line invocation: Java Test red green blue What is the result?()
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.printIn(foo. i); } } What is the result?()
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:
读代码:public class foo {static String s;public static void main (String[]args) {System.out.println (“s=” + s);}}结果是:
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:
publicclassDelta{staticbooleanfoo(charc){System.out.print(c);returntrue;}publicstaticvoidmain(String[]argv){inti=0;for(foo(‘A’);foo(‘B’)&&(i<2);foo(‘C’)){i++;foo(‘D’);}}}Whatistheresult?()
下列程序运行后的输出结果是_public class Foo{ public static void main(String[] args){ String s; System.out.println(“s=” + s); }}()
以下程序段输出的结果是() public class Test{ public static void main(String[] args) { String str=”ABCDE”; str.substring(3); str.concat(“XYZ”); System.out.println(str); } }
