printArray(int[] array):用于打印基本类型int数组的元素。它将数组的每个元素用空格分隔,并打印在一行上。 以下是使用printArray方法的示例: import java.util.Arrays; public class Main { public static void main(String[] args) { Integer[] numbers = {1, 2, 3, 4, 5}; System.out.print("Numbers: ...
publicstaticvoidsum(int[] arr){// Getting sum of array values.intsum =0;for(inti =0; i < arr.length; i++) sum += arr[i]; System.out.println("Sum of array values: "+ sum); }publicstaticvoidmain(String[] args){inta[] = {3,1,2,5,4};// Passing array to method sum.sum...
}).toArray(String[]::new); Arrays.stream(z3).forEach(System.out::println); }

Anarrayis a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You have seen an example of arrays already, in themainmethod of the "Hello World!" application. This...
toString(values)); // [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] } } 9.4.2 二分法查找 二分法检索(binary search)又称折半检索,二分法检索的基本思想是设数组中的元 素从小到大有序地存放在数组(array)中,首先将给定值 key 与数组中间位置上元素的关键码(key)比较,如果相等,则检索成功; 否则,若 key...
