java的BigDecimal比较大小
//前提为a、b均不能为null if(a.compareTo(b) == -1){ System.out.println("a小于b"); } if(a.compareTo(b) == 0){ System.out.println("a等于b"); } if(a.compareTo(b) == 1){ System.out.println("a大于b"); } if(a.compareTo(b) > -1){ System.out.println("a大于等于b"); } if(a.compareTo(b) < 1){ System.out.println("a小于等于b"); }
public class Test{ public static void main(String args[]){ Integer x = 5; System.out.println(x.compareTo(3)); System.out.println(x.compareTo(5)); System.out.println(x.compareTo(8)); } }
