我想调整输出

Question

使用以下 java 代码编辑数据，结果如下所示

[Aba , heim , 2001436]

[Eler , Nord , 2002696]

[Abe , walde , 1999297]

[Mann , Bor , 2005161]  

不幸的是，这对我没有帮助，我想更改输出，使其看起来像这样

Aba ~ heim ~ 2001436

Eler ~ Nord ~ 2002696

Abe ~ walde ~ 1999297

Mann ~ Bor ~ 2005161

这是代码

import java.io.*;

import java.util.*;

import java.util.stream.*;

public class Test {

    public static <R> Stream<R> streamOf(Iterator<R> it) {

        return StreamSupport.stream(Spliterators.spliteratorUnknownSize(it, Spliterator.ORDERED), false);

    }

    public static <R> Stream<R> reverse(Stream<R> s) {

        return streamOf(s.collect(Collectors.toCollection(ArrayDeque::new)).descendingIterator());

    }

    public static String[] reorder(String[] row) {

        int skip = row.length > 2 ? 2 : 1;

        String last = reverse(Stream.of(row).skip(skip).map(s -> s.toLowerCase().startsWith("jg.") ? s.substring(3) : s)

                .map(String::trim).filter(s -> !s.isEmpty()).filter(x -> Character.isDigit(x.charAt(0))))

                        .collect(Collectors.joining());

        String[] result = new String[3];

        result[0] = row[0];

        result[2] = last.isEmpty() ? null : last;

        if (skip == 2) {

            result[1] = row[1];

        }

        return result;

    }

    public static void main(String[] args) throws Exception {

        String str = "Aba ~ heim ~ 436~Jg.2001\n" + "Abe ~ Nord ~ 696 ~Jg.2002\n" + "Eler ~ walde ~297~Jg.1999\n"

                + "Mann ~ Bor~ 161~Jg.2005\n";

        new BufferedReader(new StringReader(str)).lines().filter(l -> !l.isEmpty()).map(l -> l.split("~"))

                .map(Test::reorder).map(Arrays::toString).forEach(System.out::println);

    }

}

更改此行：new&nbsp;BufferedReader(new&nbsp;StringReader(str)).lines().filter(l&nbsp;->&nbsp;!l.isEmpty()).map(l&nbsp;->&nbsp;l.split("~")) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.map(Test::reorder).map(Arrays::toString).forEach(System.out::println);至new&nbsp;BufferedReader(new&nbsp;StringReader(str)).lines().filter(l&nbsp;->&nbsp;!l.isEmpty()).map(l&nbsp;->&nbsp;l.split("~")) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;.map(Test::reorder).map(l->String.join("~",&nbsp;l)).forEach(System.out::println);
