// 测试new Date()毫秒值
public static void main(String[] args) {
Long id = 0L;
String Id = "";
for (int i = 0; i < 10000; i++) {
Date date = new Date();
String compare = String.valueOf(date.getTime());
if(i==0){
Id = compare;
continue ;
}
// System.out.println("ID:" + Id);
if(compare.equals(Id)){
System.out.println("i值为:"+i+";compare:" + Id);
System.out.println("值相同");
// break ;
}
Id = compare;
}
}
测试毫秒值在一段代码中的重复率
测试BigDecimal的divideAndRemainder()方法
public static void main(String[] args) {
BigDecimal bg1 = new BigDecimal("98.2");
BigDecimal bg2 = new BigDecimal("3");
BigDecimal[] divideAndRemainder = bg1.divideAndRemainder(bg2);
for (BigDecimal bigDecimal : divideAndRemainder) {
System.out.println(bigDecimal);
}
}
结果:
32.0
2.2
