java中intvalue

浮动类intValue()方法 (Float class intValue() method)

• intValue() method is available in java.lang package.

  intValue()方法在java.lang包中可用。

• intValue() method is used to return the value denoted by this Float object converted to type int (by casting).

  intValue()方法用于返回此Float对象表示的值，该值已转换为int类型(通过强制转换)。

• intValue() method is a non-static method, it is accessible with class object only and if we try to access the method with the class name then we will get an error.

  intValue()方法是一个非静态方法，只能通过类对象访问，如果尝试使用类名访问该方法，则会收到错误消息。

• intValue() method does not throw an exception at the time of conversion from float to int.

  从float转换为int时， intValue()方法不会引发异常。

Syntax:

句法：

    public int intValue();

Parameter(s):

参数：

• It does not accept any parameter.

  它不接受任何参数。

Return value:

返回值：

The return type of this method is int, it returns a converted (from type float to int) value represented by this Float object.

此方法的返回类型为int ，它返回此Float对象表示的转换后的值(从float类型转换为int类型)。

Example:

例：

// Java program to demonstrate the example
// of intValue() method of Float class
public class IntValueOfFloatClass {public static void main(String[] args) {// Variables initialization
float value1 = 10.20f;
float value2 = 20.20f;
// It returns float value denoted by this Float f1 object
// and converted to a int by calling f1.intValue()
Float f1 = new Float(value1);
// Display f1 result
System.out.println("f1.intValue(): " + f1.intValue());
// It returns float value denoted by this float f2 object
// and converted to a int by calling f2.intValue()
Float f2 = new Float(value2);
// Display f2 result
System.out.println("f2.intValue(): " + f2.intValue());
}
}

Output

输出量

f1.intValue(): 10
f2.intValue(): 20
