1、阅读程序写结果1、class V1 int a=1; void m1() System.out.println(a); class E1 extends V1 int a=2,b=3,c; void m2() System.out.println(a); class H public static void main(String s) E1 e1=new E1(); e1.m1(); e1.m2(); 2、class V1 public int x=2; V1() System.out.println(V1); class V2 extends V1 public int x=3; V2()
2、 System.out.println(V2); class H public static void main(String s) V1 e1=new V2(); System.out.println(e1.x); 3、import java.io.*;public class abc public static void main(String args ) AB s = new AB(Hello!); System.out.println(s.toString( ); class AB String s1; String s2; AB( String str1 , String str2
3、 ) s1 = str1; s2 = str2; public String toString( ) return s1+s2;4、 import java.io.* ; public class abc public static void main(String args ) int i , s = 0 ; int a = 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , 90 ; for ( i = 0 ; i a.length ; i + ) if ( ai%3 = = 0 ) s += ai ; System.out.println(s=+s); 5、
4、class V1 public int x=4; V1() System.out.println(V1); class V2 extends V1 public int x=7; V2() System.out.println(V2); class H public static void main(String s) V1 e1=new V2(); System.out.println(e1.x); 6、class V1 int a=3; void m1() System.out.println(a); class E1 extends V1 int a=5,b=3,c; void m2()
5、 System.out.println(a); class H public static void main(String s) E1 e1=new E1(); e1.m1(); e1.m2(); 阅读程序，给出程序的功能1、public class H public static void main(String args) Fact N=new Fact(4); System.out.print(N.fact(); class Fact int n; Fact(int nn) n=nn; int fact() int i,f=1; for(i=1;i=n;i+) f=f*i; retur
6、n f; 2、public class H public static void main(String args) int i,Max,Min; int a=12,67,8,98,23,56,124,55,99,100; Max=a0;Min=a0; for(i=1; ia.length;i+) if(aiMax) Max=ai; System.out.print(Max+ +Min); import java.io.*; public class abc public static void main(String args) SubClass sb = new SubClass( );
7、System.out.println(sb.max( ); class SuperClass int a = 10 , b = 20 ; class SubClass extends SuperClass int max( ) return (ab)?a:b); 3、import java.io.* ;public class abc public static void main(String args ) int i , n = 10 , max = 0 , min = 0 , temp = 0; try BufferedReader br = new BufferedReader( ne
8、w InputStreamReader(System.in); max = min = Integer.parseInt(br.readLine( ); catch ( IOException e ) ; for ( i = 2 ; i max ) max=temp; if (temp min) min=temp; catch ( IOException e ) ; System.out.println(max=+max+nmin=+min); 4、import java.awt.*; public class abc public static void main(String args)
9、new FrameOut(); class FrameOut extends Frame Button btn; FrameOut( ) super(button); btn = new Button(click); setLayout(new FlowLayout( ); add(btn); setSize(300,200); show( ); 5、public class Sum public static void main( String args ) double sum = 0.0 ; for ( int i = 1 ; i = 100 ; i + + ) sum += 1.0/(double) i ; System.out.println( sum=+sum ); 6、import java.io.* ; public class Reverse public static void main(String args ) int i , n =10 ; int a = new int10; for ( i = 0 ; i = 0 ; i ) System.out.print(ai+ ); System.out.println( );
