int index = 1; int [] foo = new int [3]; int bar = foo [index]; int baz = bar + index; What is the result?()
为将数组myArray的长度由3改为6,现采取以下编码: int[]myArray=new int [3]; myArray=new int[6]; 代码执行后,以下叙述哪项是正确的?()
1. public class X { 2. public static void main (String[]args) { 3. int [] a = new int [1] 4. modify(a); 5. System.out.printIn(a[0]); 6. } 7. 8. public static void modify (int[] a) { 9. a[0] ++; 10. } 11. } What is the result?()
Given: 8.int index = 1: 9.Boolean [] test = new boolcan [3]; 10.boolcan foo = test [index]; What is the result()?
11.public static void main(String[]args){ 12.Object obj=new int[]{1,2,3}; 13.int[] someArray=(int[])obj; 14.for(inti:someArray)System.out.print(i+"") 15.} What is the result?()
11. public static void main(String[] args) { 12. Object obj =new int[] { 1,2,3 }; 13. int[] someArray = (int[])obj; 14. for (int i: someArray) System.out.print(i +“ “) 15. } What is the result? ()
1. public class A { 2. public String doit(int x, int y) { 3. return “a”; 4. } 5. 6. public String doit(int... vals) { 7. return “b”; 8. } 9. } Given: 25. A a=new A(); 26. System.out.println(a.doit(4, 5)); What is the result?()
1. public class Boxer1 { 2. Integer i; 3. int x; 4. public Boxer1(int y) { 5. x=i+y; 6. System.out.println(x); 7. } 8. public static void main(String[] args) { 9. new Boxer1(new Integer(4)); 10. } 11. } What is the result?()
以下程序执行的结果是什么?() int[] myArray = new int[3]; try{ for(int i=0; i<=myArray.length;i++){ myArray[i]=i*3; System.out.println("myArray数组的第"+i+"个元素的值是:"+myArray[i]); } }catch(ArrayIndexOurOfBoubsException e){ System.out.println("数组下标越界");}
“int[,,,]Array=new int[5,6,7,8];”语句 。
对于int a[]=new int[3];下列哪个叙述是错误的?
在Java中,以下程序编译运行后的输出结果为( )。 public class Test { int x, y; Test(int x, int y) { this.x = x; this.y = y; } public static void main(String[] args) { Test pt1, pt2; pt1 = new Test(3, 3); pt2 = new Test(4, 4); System.out.print(pt1.x + pt2.x); } }
说说下面的语法哪个是数组的定义,创建,初始化或赋值? int []a; int []a=new int[3]; int []a=new int[]{1,2,3}; int []a={1,2,3}; a[0]=1;
int[][ ] myArray3=new int[3][ ]{new int[3]{5,6,2},new int[5]{6,9,7,8,3},new int[2]{3,2}}; myArray3[2][2]的值是()。( 2 分)
1、 下面的程序段执行后,a[2]的值为() int[] a=new int[] { 7, 4, 8, 3, 6 }; int n = 5; for(int i=0; i<n-1; i++) { for(int j="0;" j++) if(a[j]> a[j+1]) { int temp=a[j]; a[j]=a[j+1]; a[j+1]=temp; } } }
声明一个数组 int()()arr = new【3】【5】; 该数组中共有()个元素。(选一项)
以下程序的运行结果为:public class A {static int k=3;public static void main(String[] args) {int k=4;A x1=new A();x1.k++;A x2=new A();x2.k++;k++;System.out.println(x1.k);}}
有如下程序: inClude using namespaCe std; Class Point{ publiC: statiC int number; publiC: Point()t.number++;} ~Point(){number--;} }; , int P0int::number=0; int main(){ Point *ptr: Point A,B; Point*ptr_point=new Point[3]; ptr=ptr_point;’ } Point C; Cout$amp;A.3
3、执行下面程序段的输出结果为()。 public class Q{ public static void main(String args[]){ int anar[]=new int[5]; System.out .println(anar[0]);} }
以下程序段输出的结果是()。 int i=1; int b,c; int a[]=new int[3]; b=a[i]; c=b+i; System.out.println()
int[] a = new int[4] { 5, 6, 4, 3 };()
