基本上我正在尝试读取一个包含以下内容的 .txt 文件:
3 5
2 3 4 5 10
4 5 2 3 7
-3 -1 0 1 5
将它们存储到二维数组中并在控制台上打印出来,我从控制台得到的结果很好,但缺少了第一行3 5,我不知道我的代码哪里出了问题,导致它忽略了第一行。现在我得到的输出结果如下:
2 3 4 5 10
4 5 2 3 7
-3 -1 0 1 5
import java.io.*;
import java.util.*;
public class Driver0 {
public static int[][] array;
public static int dimension1, dimension2;
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Welcome to Project 0.");
System.out.println("What is the name of the data file? ");
String file = input.nextLine();
readFile(file);
}
public static void readFile(String file) {
try {
Scanner sc = new Scanner(new File(file));
dimension1 = sc.nextInt();
dimension2 = sc.nextInt();
array = new int[dimension1][dimension2];
while (sc.hasNext()) {
for (int row = 0; row < dimension1; row++) {
for (int column = 0; column < dimension2; column++) {
array[row][column] = sc.nextInt();
System.out.printf("%2d ", array[row][column]);
}
System.out.println();
}
}
sc.close();
}
catch (Exception e) {
System.out
.println("Error: file not found or insufficient requirements.");
}
}
}
dimension1 = sc.nextInt()
和dimension2 = sc.nextInt()
,你将使用它们作为数组的维度。 - La VloZ
