用java补全下列代码/** * 计算数组中元素的距离 * 给定一个字符串数组strs,在给定2个字符串str1和str2,返回在strs中str1与str2的最小距离,如果str1或str2为null,或不在strs中,返回-1 * 例如: * 【数组】{"abc","cde","bcd","ac","bcd","ac"} * 【两个字符串】“abc","ac" * 【输出】最小距离为:3 */ public class AfterClassTest02 { public static void main(String[] args) { String[] strs={"abc","cde","bcd","ac","bcd","ac"}; System.out.println("数组:"+ Arrays.toString(strs)); Scanner console=new Scanner(System.in); System.out.println("请输入两个字符串:"); String str1=console.next(); String str2=console.next(); for(int i=0;i<strs.length;i++){ if(str1.equals(strs[i])){ int sort1=i; System.out.println("str1:"+(sort1+1)); } // else{ // System.out.println("str11"+"-1"); // //break; // } } for(int j=0;j<strs.length;j++) { if (str2.equals(strs[j])) { int sort2 = j; System.out.println("str2:" + (sort2 + 1)); } // else { // System.out.println("str22" + "-1"); // break; // } } } }

请补全代码如下:
```java
import java.util.Arrays;
import java.util.Scanner;
public class AfterClassTest02 {
public static void main(String[] args) {
String[] strs = {"abc", "cde", "bcd", "ac", "bcd", "ac"};
System.out.println("数组:" + Arrays.toString(strs));
Scanner console = new Scanner(System.in);
System.out.println("请输入两个字符串:");
String str1 = console.next();
String str2 = console.next();
int minDistance = calculateMinDistance(strs, str1, str2);
System.out.println("最小距离为:" + minDistance);
}
private static int calculateMinDistance(String[] strs, String str1, String str2) {
if (strs == null || strs.length == 0 || str1 == null || str2 == null) {
return -1;
}
int minDistance = Integer.MAX_VALUE;
int str1Index = -1;
int str2Index = -1;
for (int i = 0; i < strs.length; i++) {
if (strs[i].equals(str1)) {
str1Index = i;
} else if (strs[i].equals(str2)) {
str2Index = i;
}
if (str1Index != -1 && str2Index != -1) {
minDistance = Math.min(minDistance, Math.abs(str1Index - str2Index));
}
}
return minDistance == Integer.MAX_VALUE ? -1 : minDistance;
}
}
```
这段代码首先引入了`java.util.Scanner`类,用于接收用户的输入。然后,在`main`方法中,我们调用了之前编写的`calculateMinDistance`方法来计算最小距离,并将结果打印出来。
希望这次的补全能够满足你的需求!如果你还有其他问题,请随时提问。
