Ben*_*der 6 java eclipse unicode
我正在创建一个小型Java应用程序,该应用程序使用Unicode字符在Eclipse Keplar的控制台窗口中创建框的行和列。我的代码可以正常工作,但是我打印的每个Unicode字符的输出都是一个小框,而不是我要打印的Unicode字符。
我的代码如下。我有两节课。
我的主班:
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();
}
}

还有我的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。我对列,行,列宽和行宽使用4输入。

我的控制台输出看起来像什么原因?有人可以帮助我让Unicode正确显示吗?谢谢。
对我有用的是转到工作区下的首选项,并将“文本文件编码”更改为 UTF-8。
