以下是一个简单的Java示例,展示了如何将double转换为integer: java public class DoubleToIntegerConversion { public static void main(String[] args) { double doubleValue = 123.456; // 强制类型转换 int intValue = (int) doubleValue; // 输出结果 System.out.println("Double value: " + doubleValue);...
public class DoubleToIntConversion { public static void main(String[] args) { double d = 10.75; int i = (int) d; // 强制类型转换 System.out.println("Double value: " + d); System.out.println("Converted int value: " + i); } } ...
publicclassExplicitConversionExample{publicstaticvoidmain(String[]args){intintValue=58;// 声明一个int类型的变量doubledoubleValue=(double)intValue;// 显式类型转换System.out.println("int value: "+intValue);System.out.println("double value (after explicit conversion): "+doubleValue);}} 1. 2. 3...
note that this constructor provides an exact conversion; it does not give the same result as converting the double to a String using the Double.toString(double) method and then using the BigDecimal(String) constructor. To get that result, use the...

map.put("taskID", 10086); map里取出来直接转型的话会报错 (Integer) param.get("taskID") java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.Integer 解决方法 String taskId ="10086.0"; iTaskId = Double.valueOf(taskId).intValue();...
* after a narrowing primitive conversion. * @jls 5.1.3 Narrowing Primitive Conversions * * @return the {@code double} value represented by this object * converted to type {@code int} */publicintintValue(){return(int)value;} 通过以上的官方源码可以发现,这个方法需要创建Double对象,才能调用这个...
