在Java中将字符串列表转换为整数列表的程序

这是我们的字符串列表-

List<String> listString = Arrays.asList("25", "50", "75", "100", "125", "150");

现在，将字符串列表转换为整数列表-

List<Integer> listInteger = listString.stream().map(Integer::parseInt).collect(Collectors.toList());

以下是在Java中将字符串列表转换为整数列表的程序-

示例

import java.util.*; import java.util.stream.*; import java.util.function.*; public class Demo { public static void main(String[] args) { List<String> listString = Arrays.asList("25", "50", "75", "100", "125", "150"); System.out.println("List of String = " + listString); List<Integer> listInteger = listString.stream().map(Integer::parseInt) .collect(Collectors.toList()); System.out.println("List of Integer (converted from List of String) = " + listInteger); } }

输出结果

List of String = [25, 50, 75, 100, 125, 150] List of Integer (converted from List of String) = [25, 50, 75, 100, 125, 150]
