JDK自带函数比较大小

public static void main(String[] args) {
    int batchSize = 1000;
    int size = 10000;
    int idxLimit = Math.min(batchSize, size);
    System.out.println(idxLimit);

    idxLimit = Math.min(idxLimit + batchSize, size);
    System.out.println(idxLimit);

    idxLimit = Math.min(10001, size);
    System.out.println(idxLimit);

    idxLimit = Math.max(10001, size);
    System.out.println(idxLimit);
}
