我们如何在java的命令行参数中逐行输入

Question

I want to write a command-line argument program in java where the input one on each line rather than spaces. this is how I want to take input as command line argument

like 1 then the next input will be at next line of console

Answer 1

Scanner scan = new Scanner(System.in);
String myLine = scan.nextLine();

You'll find more information on their implementation in the API Documentation for java.util.Scanner

Answer 2

In this example, we are printing all the arguments passed from the command-line. For this purpose, we have traversed the array using for loop.

public static void main(String args[]){  

  for(int i=0;i<args.length;i++)  {
    System.out.println(args[i]);  
  }
} 

compile by > javac A.java

run by >

java A sonoo \
jaiswal \
1 \
3 \
abc  

Output:sonoo
       jaiswal
       1
       3
       abc
