如何在Java8流api中实现foreach continue或break

我有以下代码,我想在for each中中断或继续回路:-

 List<Map<String, Object>> dataSource = new ArrayList<>();
Map<String, Object> rowMap2 = new LinkedHashMap<>();
  dataSource.stream().forEach(item -> {
        Map<String, Object> rowMap2 = new LinkedHashMap<>();
        if(item.get("Security").toString().equals("SECURITIES")){
            rowMap2 = item;
            for(Map.Entry<String, Object> entry : rowMap2.entrySet()){
                if(entry.getKey().equalsIgnoreCase("Security")){
                    entry.getKey().replace(entry.getKey(), mainType);
                }
            }
            dataSource2.add(rowMap2);
            // I want to continu here. 
        }
        if(entry.getKey().equals("Stock")){
            rowMap2.put(mainType, "SECURITIES");
            rowMap2.put(subType, entry.getValue());

            dataSource2.add(rowMap2);
            // I want to break from this loop here
        }
        dataSource2.add(rowMap2)
        }); 

请告诉我怎么做?
