Question

    public static void main(String[] args) {

        String[] names = {"Regina Kareem Obrien","Gretchen Brewer","Marty Cox","Roxie Blankenship","Stacey Trujillo","Ahmad James","Jordan Sykes","Frankie Hodge","Marguerite Doyle","Wilmer Baldwin"};
        String[] address = {"Avenida Ressano Garcia","Rua Roberto Duarte Silva","Avenida de Roma","Rua da Betesga","Rua Damasceno Monteiro","Rua de São Julião","Rua de São Mamede","Rua do Comércio","Rua do Salitre","Rua dos Bacalhoeiros"};
        String[]  dob = {"1999/8/26","2008/5/24","2002/10/7","2010/1/26","2005/11/21","2007/4/9","1999/8/26","2008/5/24","2002/10/7","2010/1/26"};
        int[] phone = {607544367,604903566,411315929,261809725,538236027,442128744,117255969,241273904,666757780,316948768};

        for (int i = 0; i < 10; i++){
            System.out.println("Name: " + names[i] + " Address: " + address[i] + " DOB: " + dob[i] + " Phone: " + phone[i]);
        }
    }

这样打印出来：

Name: Regina Kareem Obrien Address: Avenida Ressano Garcia DOB: 1999/8/26 Phone: 607544367
Name: Gretchen Brewer Address: Rua Roberto Duarte Silva DOB: 2008/5/24 Phone: 604903566
Name: Marty Cox Address: Avenida de Roma DOB: 2002/10/7 Phone: 411315929
Name: Roxie Blankenship Address: Rua da Betesga DOB: 2010/1/26 Phone: 261809725

Name: Wilmer Baldwin Address: Rua dos Bacalhoeiros DOB: 2010/1/26 Phone: 316948768

是否可以格式化输出格式化的方式？

我想要这样的事情：

Name: Regina Kareem Obrien   Address: Avenida Ressano Garcia       DOB: 1999/8/26  Phone: 607544367
Name: Gretchen Brewer        Address: Rua Roberto Duarte Silva     DOB: 2008/5/24  Phone: 604903566
Name: Marty Cox              Address: Avenida de Roma              DOB: 2002/10/7  Phone: 411315929
Name: Roxie Blankenship      Address: Rua da Betesga               DOB: 2010/1/26  Phone: 261809725
Name: Stacey Trujillo        Address: Rua Damasceno Monteiro       DOB: 2005/11/21 Phone: 538236027
Name: Ahmad James            Address: Rua de São Julião            DOB: 2007/4/9   Phone: 442128744
Name: Jordan Sykes           Address: Rua de São Mamede            DOB: 1999/8/26  Phone: 117255969
Name: Frankie Hodge          Address: Rua do Comércio              DOB: 2008/5/24  Phone: 241273904
Name: Marguerite Doyle       Address: Rua do Salitre               DOB: 2002/10/7  Phone: 666757780
Name: Wilmer Baldwin         Address: Rua dos Bacalhoeiros         DOB: 2010/1/26  Phone: 316948768

Answer 1

使用System.out.format(...)。例如：

System.out.format("%10s%15s%20s", s1, s2, s3)

将s1字符串填充为10，将s2字符串填充为15，将s3字符串填充为20个字符。

看看Formatter javadoc。它彻底解释了这个话题。

Answer 2

解决您的问题：

System.out.println(String.format("Name: %-20s Address: %-30s DOB: %-10s Phone: %s",
                names[i], address[i], dob[i], phone[i]));

use - 用于带空格的右边填充

Answer 3

是的，请使用System.out.printf，format string使用{{3}}指定并格式化其输出。

您可以使用带有%s参数的宽度说明符来生成正确的格式，例如：%-30s。 -很重要，它会使文字保持对齐。例如

System.out.printf("Name: %-30s, Address: %-30s...", names[i], address[i]);

玩弄它来按照你喜欢的方式进行游戏。

Answer 4

我猜\t应该对你有所帮助。试着玩这个标签，让我们这样说： System.out.println("Name: " + names[i] + "\t Address: " + address[i] + "\t DOB: " + dob[i] + "\t Phone: " + phone[i]);

Answer 5

您可以使用标签，或查看JCurses格式化控制台输出。
