单项选择题
A.x = 2
B.x = 5
C.x = 6
D.编译失败
单项选择题 class DemoApp{ public static void main(String[] args){ int x = 5; int y = ++x + x++; S ystem.out.println(“y=”+y+”,x=”+x); } } 以上程序运行后的输出结果是哪项?()
单项选择题 class Parser extends Utils { public static void main (String [] args) { try { System.out.print(new Parser().getInt("42")); } catch (NumberFormatException n) { System.out.println("NFExc "); } } int getInt(String arg) throws NumberFormatException { return Integer.parseInt(arg); } } class Utils { int getInt(String arg) { return 42; } } 结果为:()
