以下程序运行结果是 public class Test { public static void main(String[] args) { int a=1，b[]={2}; add(a); add(b); System.out.println(a+","+b[0]); } static int add(int x){ x++; return x; } static void add(int[] x){ x[0]++; } }
举一反三
- public class test1 { public static int add(int a, int b) { return a+b; } public static double add(double a, double b) { return a+b; } ________________ ___________________ { ________________ ___________________ } public static void main(String[] args) { System.out.println("调用add方法:"+add(2.1,3.4,4.5)); } }
- 以下代码的输出结果 ? public class Test1{ static int x = 3; static { ++x; } public static void main(String args[]){ System.out.println(x); } static { x++; } }
- class Demo{ public static void main(String[] args){ int x = 0; try{ x = div(1,2); }catch(Exception e){ System.out.println(e); } System.out.println(x) ; } public static int div(int a,int b){ return a / b ; } }
- 以下是"public static void test(int x, int y)"的方法重载( ) A: public static void Test(int x) B: public static int test(int x, int y) C: public static void test(int y, int x) D: public static void test(int x, int y)
- 请阅读下面的程序 public class Example { public static void main(String[] args) { int x = 1; do { x++; } while (x <= 4); System.out.println("x = " + x); } } 程序的运行结果是（）
