I new to java.I want to input studentId and studentName using Scanner and store these values to a array/s.

System.out.print("Enter StudentId :");
String studentId = input.nextLine();

System.out.print("Enter StudentName :");
String studentName = input.nextLine();

Can I store these values(not a single value) to a array?

CodePudding user response：

Try using BufferedReader

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter StudentID,StudentName");
String[] arr = br.readLine.trim().split(",");

Keep in mind

1. While inputs provide studentid and studentname as comma separated (you can change it if you want as per you requirement).
2. You need to import java.io.*;
3. This throws exception. So you can either add throws IO Exception with your main method or put all this in try catch.

Input

101, Virat

taking whole line as one input and splitting them. If input is seperated by comma, use split(",") or if seperated by space, use split(" ")

String input = sc.nextLine();
String[] myArray = input.split(" ");

input : 
R123 Ravi 

myArray will become {"R123","Ravi"}

Something like this

// short version
String[] myArray = new String[]{
        studentId,
        studentName
};
System.out.println(Arrays.toString(myArray));

// adding one by one
String[] myArray1 = new String[2];
myArray1[0] = studentId;
myArray1[1] = studentName;
System.out.println(Arrays.toString(myArray1));
