我正在创建一个小型Java应用程序，它使用Unicode字符在Eclipse Keplar的控制台窗口中创建行和列的框。我的代码运行得很好，但我打印的每个Unicode字符的输出都是一个小方框，而不是我想打印的Unicode字符。

我的代码如下所示。我有两节课。

我的主课是：

package assign03;

import java.util.Scanner;

public class Assign03 {

private static int columns;
private static int cWidth;
private static int rows;
private static int rHeight;
private static Table table;

public static void main(String[] args) {
        table = new Table();
        Scanner input = new Scanner(System.in);

        System.out.print("Enter the number of columns: ");
        columns = input.nextInt();

        System.out.print("Enter the width of the columns: ");
        cWidth = input.nextInt();

        System.out.print("Enter the number of rows: ");
        rows = input.nextInt();

        System.out.print("Enter the width of the rows: ");
        rHeight = input.nextInt();

        table.printFirstLine(columns, cWidth);

        for (int r = 0; r < rows; r++) {
            for (int rh = 0; rh < rHeight; rh++) {
                table.printVerticalLine(columns, cWidth);
            }
            if (r < (rows - 1)
                table.printInternalLine(columns, cWidth);
        }

        table.printLastLine(columns, cWidth);
        input.close();
    }
}

和我的Table.Java类：

package assign03;

public class Table {

    private char firstLine[] = { 'u2501', 'u250F', 'u2533', 'u2513' };
    private char internalLine[] = { 'u2501', 'u2523', 'u254B', 'u252B' };
    private char lastLine[] = { 'u2501', 'u2517', 'u253B', 'u251B' };
    private char verticalLine[] = { 'u2503' };
    private char whiteSpace[] = { 'u2003' };

    public void printFirstLine(int columns, int cWidth) {

        System.out.print(firstLine[1]);

        for (int c = 0; c < columns; c++) {
            for (int cw = 0; cw < cWidth; cw++) {
                System.out.print(firstLine[0]);
            }
            if (c < (columns - 1))
                System.out.print(firstLine[2]);
        }

        System.out.println(firstLine[3]);
    }

    public void printVerticalLine(int columns, int cWidth) {
        for (int c = 0; c <= columns; c++) {
            System.out.print(verticalLine[0]);
            for (int cw = 0; cw < cWidth; cw++) {
                System.out.print(whiteSpace[0]);
            }
        }
        System.out.println();
    }

    public void printInternalLine(int columns, int cWidth) {
        System.out.print(internalLine[1]);

        for (int c = 0; c < columns; c++) {
            for (int w = 0; w < cWidth; w++) {
                System.out.print(internalLine[0]);
            }
            if (c < (columns - 1))
                System.out.print(internalLine[2]);
        }

        System.out.println(internalLine[3]);
    }

    public void printLastLine(int columns, int cWidth) {

        System.out.print(lastLine[1]);

        for (int c = 0; c < columns; c++) {
            for (int w = 0; w < cWidth; w++) {
                System.out.print(lastLine[0]);
            }
            if (c < (columns - 1))
                System.out.print(lastLine[2]);
        }

        System.out.println(lastLine[3]);
    }
}

当应用程序运行时，输出如下所示。我使用4作为列、行、列宽和行宽的输入值。

为什么我的控制台输出看起来是这样的？有谁能帮我把Unicode正确显示出来吗？谢谢。
