Java运行程序写结果

1 Java 练习题 四 运行程序写结果 1 当在命令提示符后输入 java SumTest 4 5 之后 下列程序的输出结果为 4 5 9 public class SumTest public static void main String args int a b sum a Integer parseInt args 0 b Integer parseInt args 1 sum a b System out println a b sum 2 当在命令提示符后输入 java PrintStar 8 之后 下列程序的输出结果为 A12 public class PrintStar public static void main String args int n Integer parseInt args 0 int i for i 1 i n i System out print System out println 3 当在命令提示符后输入 java CalculateTest 5 5 之后 下列程序的输出结果为 10 0 public class CalculateTest public static void main String args float x y x Float parseFloat args 0 if x 1 y x else if 1 x 2 else y 3 x 11 System out println y 4 下列程序的输出结果为 null A11 public class X public static void main String args String names new String 5 for int x 0 x args length x names x args x System out println names 2 5 下列程序的输出结果为 9 5 10 0 8 A12 public class Test public static void main String args System out print 3 5 1 2 56 10 System out print 3 5 1 0 2 56 10 int a 4 3 7 1 System out println a 6 运行结果是 Hi Like B12 public class Test1 String str new String Hi char ch L i k e public static void main String args Test1 ex new Test1 System out print ex str System out print ex ch 7 运行结果是 4 6 8 10 12 14 16 18 20 B12 3 public class Test3 public static void main String args int i for i 3 i 20 i if i 2 0 System out print i 8 运行结果是 0 1 2 3 4 5 6 7 8 9 class Test6 public static void main String args int i for i 0 i 10 i System out print i if i 2 0 continue System out println 9 运行结果是 3 5 7 11 13 17 19 23 29 public class Test14 public static void main String args int n 1 m j i for i 3 i 30 i 2 m int Math sqrt double i for j 2 j m 1 System out print i if n 5 0 System out print n n 10 下列程序的输出结果为 7 8 15 5 8 13 class generalFunction public static int add int x int y return x y 静态方法 public class StaticFunTest public static void main String args int c generalFunction add 7 8 System out print 7 8 c generalFunction fun new generalFunction int d fun add 5 8 System out println 5 8 d Aclass 11 下列程序的输出结果为 Bclass A11 A12 class Aclass void go System out println Aclass public class Bclass extends Aclass void go System out println Bclass public static void main String args 5 Aclass a new Aclass Aclass a1 new Bclass a go a1 go 12 运行结果是 What a pleasure A12 I am I am Lucy Hello public class Test13 extends TT public static void main String args Test13 t new Test13 public Test13 String s super s System out println Hello public Test13 this I am Lucy class TT public TT System out println What a pleasure public TT String s this System out println I am s 13 运行结果是 36 B12 class Test11 class Dog private String name private int age public int step Dog String s int a 6 name s age a step 0 public void run Dog fast fast step public static void main String args Test11 a new Test11 Dog d a new Dog Kate 5 d step 35 d run d System out println d step 14 运行结果是 exception000 finished public class Test10 public static void aMethod throws Exception try throw new Exception catch Exception e System out println exception000 public static void main String args try aMethod catch Exception e System out println exception 7 System out println finished 15 运行结果是 相等相等 B12 public class Test7 public static void main String args String s1 Java program String s2 new String Java program if s1 equals s2 System out println 不相等 else System out println 相等 16 在输入整数的提示后输入 8 在输入符号的提示后输入 那么下列程序的输出结果为 A12 import java util class CharTest public static void main String args Scanner reader n
