java中的重新排列字符串

Question

所以我的问题是我让这样说的字符串或数组：

String a = "cola";
String b = "5000";
String k = a + " | " + b;
String BigIn = "----------";

输出是：-

----------------------
Cola | 5000
TestAnotherOne | 6000
----------------------

我需要做的是重新排列输出，就像这样：-

----------------------
Cola           | 5000
TestAnotherOne | 6000
Anotheronebut  |
BigString      | 7000
----------------------

因此|被卡在字符串中了

是否有帮助？

我使用pring 2d来打印帐单，我用来执行此操作的类是：-

public PageFormat getPageFormat(PrinterJob pj) {

    PageFormat pf = pj.defaultPage();
    Paper paper = pf.getPaper();

    double middleHeight = 99999;
    double headerHeight = 2.0;
    double footerHeight = 2.0;
    double width = convert_CM_To_PPI(8);      //printer know only point per inch.default value is 72ppi
    double height = convert_CM_To_PPI(headerHeight + middleHeight + footerHeight);
    paper.setSize(width, height);
    paper.setImageableArea(
            0,
            2,
            width,
            height - convert_CM_To_PPI(1)
    );   //define boarder size    after that print area width is about 180 points

    pf.setOrientation(PageFormat.PORTRAIT);           //select orientation portrait or landscape but for this time portrait
    pf.setPaper(paper);

    return pf;
}

protected static double convert_CM_To_PPI(double cm) {
    return toPPI(cm * 0.393600787);
}

protected static double toPPI(double inch) {
    return inch * 72d;
}

public class BillPrintable implements Printable {

    @Override

Answer 1

为了解决此问题，我使用了具有固定字体的另一种字体类型：-

 g2d.setFont(new Font("monospaced", Font.PLAN, 14));

代替

g2d.setFont(new Font("TimesRoman", Font.CENTER_BASELINE, 14));
