如何处理运行rjava时出现的"Java Heap Space“错误

import java.util.ArrayList;
import java.util.List;

public class Example {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        for (int i = 0; i < 1000000; i++) {
            list.add(new String("Item " + i));
        }
    }
}

import java.util.ArrayList;
import java.util.List;

public class Example {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        int batchSize = 10000;
        for (int batch = 0; batch < 100; batch++) {
            for (int i = 0; i < batchSize; i++) {
                list.add(new String("Item " + (batch * batchSize + i)));
            }
            // 处理当前批次的数据
            processBatch(list);
            list.clear(); // 清空列表，释放内存
        }
    }

    private static void processBatch(List<String> list) {
        // 处理数据的逻辑
    }
}
