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对象的各...
package Hello; import java.util.Scanner; public class hello_test { public static void main(String[] args) { // TODO Auto-generated method stub Scanner in=new Scanner(System.in);//创建扫描器 int[] numbers=new int[100];//数组 double sum=0; for(int i=0;i<5;i++)//输入5个数 { i...
2. Take 10 integer inputs from user and store them in an array. Now, copy all the elements in an another array but in reverse order. packagecom.codesdope;importjava.util.Scanner;publicclassCopyElementsReverseOrder{publicstaticvoidmain(String[] args){Scanners=newScanner(System.in);int[] my_...
Sample Solution: Java Code: importjava.util.*;publicclassMain{publicstaticvoidmain(String[]args){Scannerscan=newScanner(System.in);int[]nums=newint[]{0,1,2,3,5,7,9,12,15,17,18,21,25,32,52,54,75,89,90,93,97,104,120};System.out.println("Original array:");System.out.println(Ar...
Using Scanner Class In the above example, we had mentioned that, the inputs are taken making use of the scanner class. Scanner class in Java is that class which reads input at runtime given by the tester/user for any primitive datatype. So here, we make use of the scanner class to...

Traversing a String type array is an extremely simple process. The most efficient process for traversing the elements of a String type array in java is using loops. For this purpose, a for-loop can be used that loops from 0 to the total length of array -1 index. The following example ...
