public class StreamTest {
    public static void main(String[] args) {
        List<String> resultList = Arrays.asList("a", "b", "c");

        // allMatch：判断集合中的所有元素都是满足条件,返回true
        boolean allMatch = resultList.stream().allMatch(param -> param.equals("a"));

        // anyMatch：判断集合中的其中一个元素满足条件，返回true
        boolean anyMatch =resultList.stream().anyMatch(param->param.equals("a"));

        // noneMatch：判断集合中的所有元素都不满足条件，返回true
        boolean noneMatch =resultList.stream().noneMatch(param->param.equals("a"));

        System.out.println("allMatch="+allMatch);
        System.out.println("anyMatch="+anyMatch);
        System.out.println("noneMatch="+noneMatch);

    }
}

执行结果：

allMatch=false
anyMatch=true
noneMatch=false
