Java 将数字数组转换为CSV字符串的最佳方法？

如果我有一个

字符串[]

（假设没有逗号），我可以简单地生成一个CSV行。例如：

String[] header = {"header0", "header1", "header2"};
String joined = String.join(",", header);

用say

int[]vals01={0,1,2}做等效的好方法是什么？（我考虑使用<代码>数组。toStase并将结束部分切片为丑。）< /P> < P>考虑使用新的（java 8）。< /P>
对于
字符串[]
：

String[] header = {"header0", "header1", "header2"};
StringJoiner joiner = new StringJoiner(",");
Arrays.stream(header).forEach(joiner::add);
String joined = joiner.toString();

int[] ints = {1, 2, 3};
StringJoiner joiner = new StringJoiner(",");
Arrays.stream(ints).forEach(i -> joiner.add(Integer.toString(i)));
String joined = joiner.toString();
System.out.println(joined);

对于
int[]
的情况：

String[] header = {"header0", "header1", "header2"};
StringJoiner joiner = new StringJoiner(",");
Arrays.stream(header).forEach(joiner::add);
String joined = joiner.toString();

int[] ints = {1, 2, 3};
StringJoiner joiner = new StringJoiner(",");
Arrays.stream(ints).forEach(i -> joiner.add(Integer.toString(i)));
String joined = joiner.toString();
System.out.println(joined);

这可以通过一行程序中的Streams API完成：

Arrays.stream(new int[] {0, 1, 2}).mapToObj(String::valueOf).collect(joining(","));

（假设
导入静态java.util.stream.collector.joining
）
