如何在Java中将字符串数组中存储的值转换为整数数组

这里我想将sting数组值转换为整数数组，需要将所有字符串值存储为整数数组，下面是字符串数组：

private String[] aa = {"70","80","99","140","150","199","200","300",
                       "349","350","400","499","500","501","900","1000","1100","1200"};

int[]bb=新的int[aa.length]；
对于（int i=0；i

---

循环遍历数组并将其转换为int

int []intArray = new int[strArray.length];
int i = 0;
for(String s : strArray)
  intArray[i ++] = Integer.parseInt(s);
System.out.println(Arrays.toString(intArray));

---

如果您使用的是Java8，您可以：

int[] array = Stream.of(aa).mapToInt(Integer::parseInt).toArray();

---

到目前为止，您的尝试是什么？副本：

int[] array = Stream.of(aa).mapToInt(Integer::parseInt).toArray();
