编程:输入两个数组arr1[ ],arr2[],调用函数swap2(arr1,arr2,3),来交换arr1与arr2

编程：输入两个数组arr1[ ]、arr2[]，调用函数swap2(arr1,arr2,3)，来交换arr1与arr2两数组的第3个元素值，输出交换后的结果，编写完整程序。

Answer 1

public class Test {
public static void main(String[] args) {
int [] arrA = new int[]{12,33,4,15,55};
int [] arrB = new int[]{6,73,11,93,3};
swap(arrA,arrB,1);

}

public static void swap(int [] a ,int [] b, int c){
int temp = 0;
if(c>0&&c<a.length&&c<b.length){
temp = a[c-1];
a[c-1] = b[c-1];
b[c-1] = temp;
for (int i = 0; i < a.length; i++) {
System.out.print(" "+a[i]+" ");
}
System.out.println("--------------------------------------------");
for (int i = 0; i < b.length; i++) {
System.out.print(" "+b[i]+" ");
}
}else{
System.out.println("输入有效的位置数");
}

}
}
