代码

package com.nash.java.pop.ch06_math;

public class MathApp {

    /**
     * Math 静态类方法
     * @param args
     */
    public static void main(String[] args) {

        System.out.println("Math.max(2,10):\t " + Math.max(2,10));
        System.out.println("Math.max(2.6,7.5):\t " + Math.max(2.6,7.5));
        System.out.println("Math.abs(-100):\t " + Math.abs(-100));
        System.out.println("Math.abs(-100.30):\t " + Math.abs(-100.30));
        System.out.println("Math.acos(1):\t " + Math.acos(1));
        System.out.println("Math.ceil(2.6):\t " + Math.ceil(2.6));
        System.out.println("Math.floor(2.6):\t " + Math.floor(2.6));
        System.out.println("Math.exp(Math.E):\t " + Math.exp(Math.E));
        System.out.println("Math.min(2,10):\t " + Math.min(2,10));
        System.out.println("Math.round(2.6):\t " + Math.round(2.6));
        System.out.println("Math.random():\t " + Math.random());
    }
}
