importjava.util.Arrays; // 导入util.Arrays类
publicclass Test {
public static void main(String[] unused) {
String[] str = {"xxx","zzz","yyy","aaa"}; //定义字符串数组
Arrays.sort(str); //对字符串数组的内容进行排序
intindex=Arrays.binarySearch(str,"zzz"); //使用二分法查找字符串数组str中是否包含“zzz”字符串
if(index==-1) // binarySearch函数如果查找失败即返回-1
System.out.println("no"); //打印no
else
System.out.println("yes"); //如果找到,打印yes
}
}
