长类intValue()方法 (Long 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 Long object converted to type int (by casting).

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

• intValue() method is a non-static method, it is accessible with the 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，如果尝试使用类名称访问该方法，则会收到错误消息。

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

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 long to int) value represented by this Long object.

此方法的返回类型为int ，它返回一个由此Long对象表示的转换后的值(从long型到int型)。

Example:

例：

// Java program to demonstrate the example
// of intValue() method of Long class
public class IntValueOfLongClass {public static void main(String[] args) {// Variables initialization
long value1 = 100;
long value2 = 200;
// It returns long value denoted by this Long ob1 object
// and converted to a int by calling ob1.intValue()
Long ob1 = new Long(value1);
// Display ob1 result
System.out.println("ob1.intValue(): " + ob1.intValue());
// It returns long value denoted by this Long ob2 object
// and converted to an int by calling ob2.intValue()
Long ob2 = new Long(value2);
// Display ob2 result
System.out.println("ob2.intValue(): " + ob2.intValue());
}
}

Output

输出量

ob1.intValue(): 100
ob2.intValue(): 200
