返回值：

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

此方法的返回类型为int ，它返回由此Number对象表示的转换后的值(从类型号转换为int)。

Example:

例：

// Java program to demonstrate the example 
// of intValue() method of Number class
public class IntValueOfNumberClass {
public static void main(String[] args) {
// Variables initialization
float f1 = 10.58f;
double d1 = 20.62;
// It returns int value denoted by this object
// and converted to a int by calling f.intValue()
Float f = new Float(f1);
// Display f result
System.out.println("f.intValue(): " + f.intValue());
// It returns int value denoted by this object
// and converted to a int by calling d.intValue()
Double d = new Double(d1);
// Display d result
System.out.println("d.intValue(): " + d.intValue());
}
}

Output

输出量
