下面是一个示例代码: publicclassTruncateDecimal{publicstaticvoidmain(String[]args){doublenum=3.14159;intresult=(int)num;System.out.println("直接舍弃小数后的数据为:"+result);}} 1. 2. 3. 4. 5. 6. 7. 在上面的代码中,我们声明了一个double类型的变量num,并赋值为3.14159。然后我们将num转换为int...
BigDecimal是Java中用于处理高精度运算的类,通过设置精度和舍入模式,我们可以实现对浮点数的截断操作。 importjava.math.BigDecimal;publicclassTruncateDecimalExample{publicstaticvoidmain(String[]args){doublenumber=3.1415926;BigDecimalbd=newBigDecimal(number);BigDecimaltruncatedNumber=bd.setScale(2,BigDecimal.ROUND_DOW...

in Java. As I said, it's very easy to convert one data type to another in Java, and double and long is no different. In my opinion, you should just cast a double value too long if you are not interested in decimal value or just want to truncate the decimal part of a double ...
How to Convert a Double to an Int in Java Using theintValue()Method In Java, theDoublewrapper class provides a convenient method calledintValue()for converting adoublevalue to anint. This built-in method simplifies the conversion process by directly removing the digits after the decimal point ...
Data of types int, long, float, and double, as well as references to instances of class String, are managed using the ldc, ldc_w, and ldc2_w instructions. The ldc and ldc_w instructions are used to access values in the run-time constant pool (including instances of class String) ...

double 8 0.0d Double boolean - false Boolean char 2 \u0000(null) Character 注: 1.int是基本数据类型,Integer是int的封装类,是引用类型。int默认值是0,而Integer默认值是null,所以Integer能区分出0和null的情况。一旦java看到null,就知道这个引用还没有指向某个对象,再任何引用使用前,必须为其指定一个对象...
