对Double类型数据进行截取

1、对Double类型数据进行截取（转换方法1）public static void main(String[] args) { Double ss = 18000.2; String test = ss+""; String NewNum = test.substring(0,test.length()-4)+"."+test.substring(test.length()-4,test.length()-2); Double fromString = new Double(NewNum); System.out.println(fromString);}

2、对Double类型数据进行截取（转换方法2）public static void main(String[] args) { Double ss = 18000.2; String test = ss+""; String NewNum = test.substring(0,test.length()-4)+"."+test.substring(test.length()-4,test.length()-2); Double doubleString = Double.parseDouble(NewNum); System.out.println(doubleString);}
