텍스트 파일에서 한 줄로 공백을 나누는 방법

Question

JTable으로 text/excel 파일을 읽으려고합니다. 그러나 행에 하나의 행으로 표시되지만 헤더에 의존하지는 않습니다. 나는 헤더도 얻지 못한다.

분할에 대한

public class TableTest extends JFrame { 

    //create row and col as vector 
    private Vector data; 
    private Vector column; 
    private final JPanel pane;

     //set the title 
     super("Table test");

     setSize(400, 400); 

     //make frame visible 
     setVisible(true); 

     //close when click the cross button 
     setDefaultCloseOperation(EXIT_ON_CLOSE);

Answer 1

공백 시도에 기초하여 문자열,

String.split("\\s"); 

Answer 2

은 또한 사용할 수 있습니다

String[] split = StringUtils.split(stringToSplit, " ");
