导入Scanner类:在代码的开头,使用import java.util.Scanner;语句导入Scanner类,以便在代码中使用它。 创建Scanner对象:使用Scanner scanner = new Scanner(System.in);语句创建一个Scanner对象,用于从标准输入读取数据。如果要从文件中读取数据,可以将System.in替换为文件路径。 使用Scanner读取输入:使用Scanner对象...

In the above program first, we sort the input array since for binarySearch the array should be sorted. Then the array and the key to be searched are passed to the ‘binarySearch’ method. The index at which the key is found is displayed in the output. Prototype:static int binarySearch (i...
