A: 程序报错
B: 10 20 30
C: 1 2 3 4 5
D: 1 2 3
举一反三
- 下面代码的运行结果是。 public class Test { public static void main(System[] args){ int[ ] a ={10,20,30}; int[ ] b ={1,2,3,4,5}; a=b; for (int i=0;i<a.length;i++){ System.out.print(a[i]+” ”); } } }[/i]
- 下面代码的运行结果是_____________。 public class Test{ public static void main(String[] args){ int[] a=new int[3]; int[] b= new int[]{1,2,3,4,5}; a=b; for(int i=0; i<b.length; i++){ System.out.print(a[i]+" "); } } }[/i]
- 下列程序的运行结果是（）。 public class Test public static void main ( String [ ] args ) int count = 0 for( int i = 1 i < 5 i = 2) for( int j = 1 j< = 10 j = 3) count System .out .print (count ) _
- 以下程序的输出结果是【 】。 class Program { public static void Main(string[] args) { int[] a = new int[3] { 1, 2, 3 }; for (int i = 0; i < 3; i++) Console.Write("{0} ", a[i]); Console.WriteLine(); int[] b = a; for (int i = 0; i < 3; i++) b[i] = 2 * b[i]; for (int i = 0; i < 3; i++) Console.Write("{0} ", a[i]); Console.WriteLine(); Console.Read(); } }[/i][/i][/i][/i]
- using System; class Test { public static void Main () { int[ ] a ={2,4,6,8,10,12,14,16,18}; for (int i=0; i<9; i++) { Console.write(“ ”+a[i]); if ((i+1)%3==0) Console.writeLine(); } } }[/i]

下列代码段执行后的结果是()int[] a = { 1, 3, 5, 2, 4 };int j = 4;for (int i = 0; i <; 5; i++) { a[i] = a[j]; j--;}for (int i = 0; i <; 5; i++) System.out.print(a[i] + " ");[/i][/i] A: 1 2 3 4 5 B: 5 4 3 2 1 C: 4 2 5 2 4 D: 4 2 5 3 1

请阅读下面的程序 public class Test { public static void main(String[] args) { int a = { 2, 0, 4, 1, 8, 3, 5 }; int temp; for (int i = 0; i < a.length - 1; i++) { for (int j = a.length - 1; j > i; j--) { if (aj < aj - 1) { temp = aj; aj = aj - 1; aj - 1 = temp; } } } for (Integer i : a) { System.out.print(i); } }} 下列选项中,哪个是程序的运行结果() A: 8543210 B: 0123458 C: 2041835 D: 以上答案都不对
