我正在尝试学习 Java 8。有没有办法将下面的方法转换为 Java 8 Streams、filter 和 forEach。如果是这样，如何？

String[] couponList = coupons.split(",");

for(String coupon:couponList) {
  singleCouponUsageCount = getSingleCouponUsageCount(coupon);
  if(singleCouponUsageCount >= totalUsageCount)
    return 0;
}
return 1;

//

for(String coupon:couponList) {
  singleCouponUsageCount = getSingleCouponUsageCount(coupon);
  if(singleCouponUsageCount >= totalUsageCount)
    return singleCouponUsageCount;
}
return singleCouponUsageCount;
