例如:System.out::println等同于x->System.out.println(x),String::toLowerCase等同于x->x.toLowerCase(),BigDecimal::new等同于x->new BigDecimal(x)。 二、用法示例 为充分体现Optional类的“威力”,首先以组合方式定义Location和Person两个类。 Location类: public class Location { private String country; ...
// so we have to fill it to be a 8 digit binary string // b=b+100000000(2^8=256) then only get the lower 8 digit b |= 256; // mark the 9th digit as 1 to make sure the string // has at // least 8 digits String str = Integer.toBinaryString (b); int len = str.lengt...
