在我的OrderBy函数中，我在哪里使用我的字符串到数值函数？

const data = [
  { id: 1, value: '10' },
  { id: 2, value: '5' },
  { id: 3, value: '20' }
];

data.sort((a, b) => parseInt(a.value, 10) - parseInt(b.value, 10));

console.log(data);

data = [
  {'id': 1, 'value': '10'},
  {'id': 2, 'value': '5'},
  {'id': 3, 'value': '20'}
]

sorted_data = sorted(data, key=lambda x: int(x['value']))

print(sorted_data)

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

class Data {
  int id;
  String value;

  Data(int id, String value) {
    this.id = id;
    this.value = value;
  }

  @Override
  public String toString() {
    return "Data{" +
            "id=" + id +
            ", value='" + value + '\'' +
            '}';
  }
}

public class Main {
  public static void main(String[] args) {
    List<Data> dataList = new ArrayList<>();
    dataList.add(new Data(1, "10"));
    dataList.add(new Data(2, "5"));
    dataList.add(new Data(3, "20"));

    Collections.sort(dataList, new Comparator<Data>() {
      @Override
      public int compare(Data a, Data b) {
        return Integer.parseInt(a.value) - Integer.parseInt(b.value);
      }
    });

    for (Data data : dataList) {
      System.out.println(data);
    }
  }
}
