public class Main {
public static void main(String[] args) {
float f = (float) 1 / 0;
boolean b1 = Float.isInfinite(f);
System.out.println(b1);
Float fObj = new Float(f);
boolean b2 = fObj.isInfinite();
System.out.println(b2);
}
}
运行结果如下:
public class Main {
/*from www. j a va 2 s. c o m*/
public static void main(String[] args) {
float f = (float) Math.sqrt(-10);
boolean b1 = Float.isNaN(f);
System.out.println(b1);
Float fObj = new Float(f);
boolean b2 = fObj.isNaN();
System.out.println(b2);
}
}
运行结果如下:
【float】
