问题描述

帮我解答这个问题

解决方案

  class  IntersectionUnion 
{
static int [] Intersection( int [] p1, int [] p2){
int count = 0 ;
for int i = 0 ; i < p1.length; i ++){
for int j = 0 ; j < p2.length ; j ++){
if (p1 [i] == p2 [j]){
count ++;
break ;
}
}
}
int [] result = new int [count];
count = 0 ;
for int i = 0 ; i < p1.length; i ++){
for int j = 0 ; j < p2.length ; j ++){
if (p1 [i] == p2 [j])
{
result [count ++] = p1 [一世];
break ;
}
}
}
返回结果;
}
静态 int [] Union( int [] p1, int [] p2){
int count = 0 ;
for int i = 0 ; i < p1.length; i ++){
for int j = 0 ; j < p2.length ; j ++){
if (p1 [i]!= p2 [j]){
count ++;
break ;
}
}
}
int [] result = new int [count];
count = 0 ;
for int i = 0 ; i < p1.length; i ++){
for int j = 0 ; j < p2.length ; j ++){
if (p1 [i]!= p2 [j])
{
result [count ++] = p1 [一世];
break ;
}
}
}
返回结果;
}

static int [] sortArray( int [] numarray)
{
int max = numarray.length;
for int i = 1 ; i < max; i ++){
for int j = 0 ; j < max - i; j ++ ){
if (numarray [j] > numarray [j + 1 ]){
int temp = numarray [j];
numarray [j] = numarray [j + 1 ];
numarray [j + 1 ] = temp;
}
}
}
返回 numarray;
}
静态 int [] Find_Unique_Elements( int [] numarray)
{
sortArray(numarray);
int element = numarray [ 0 ];
int count = 1 ;
for int i = 1 ; i < numarray.length; i ++)
{
if (element == numarray [i])
continue ;
else
{
element = numarray [i];
count ++;
}
}
int [] result = new INT [数];
count = 0 ;
元素= numarray [ 0 ];
结果[count ++] = element;
for int i = 1 ; i < numarray.length; i ++){
if (element == numarray [i])
继续;
else
{
element = numarray [i];
结果[count ++] = element;
}
}
返回结果;
}
public static void main( String [] args)
{
int [ ] array1 = new int [] { 10 20 30 40 50 60 70 80 90 100 95 85 75 65 55 45 35 25 ,< span class =code-digit> 15 , 05 10 15 20 25 30 35 40 45 50 55 };
int [] array2 = new int [] { 15 25 35 45 55 12 22 32 43 52 15 25 35 45 55 };
int [] p1 = Find_Unique_Elements(array1);
int [] p2 = Find_Unique_Elements(array2);
int [] InterRes = Intersection(array1,array2);
int [] unionRes = Union(arra1,array2);
系统。 out .print( \\第一个数组中的唯一排序元素:);
for int i = 0 ; i < p1.length; i ++)
System。 out .print( p1 [i] + );
系统。 out .print( \\第二个数组中的唯一排序元素:);
for int i = 0 ; i < p2.length; i ++)
System。 out .print( p2 [i] + );
系统。 out .print( \\ \\ n \\ n \\ n共同(交集)元素:);
for int i = 0 ; i < InterRes.length; i ++)
System。 out .print( InterRes [i] + );
for int i = 0 ; i < unionRes.length; i ++)
System。 out .print( unionRes [i] + );
}
}





试试吧,不会工作。

一切顺利
