问题4：JAVA各大数据类型能存的最大值和最小值：包括char,byte,int,long,float,double等.float和double分别用科学计数法和非科学计数法输出。

下面为代码和输出结果：

<pre name="code" class="java">package p1;public class test3 {public static void main(String[] args) {System.out.println("\nCharacter：");System.out.printf("Double.MIN_VALUE = %h\n",Character.MIN_VALUE);System.out.printf("Double.MAX_VALUE = %h\n",Character.MAX_VALUE);System.out.println("\nByte：");System.out.println("Byte.MIN_VALUE = " + Byte.MIN_VALUE);          System.out.println("Byte.MAX_VALUE = " + Byte.MAX_VALUE);         System.out.println("\nShort：");System.out.println("Short.MIN_VALUE = " + Short.MIN_VALUE);          System.out.println("Short.MAX_VALUE = " + Short.MAX_VALUE);         System.out.println("\nInteger：");        System.out.println("Integer.MIN_VALUE = " + Integer.MIN_VALUE);          System.out.println("Integer.MAX_VALUE = " + Integer.MAX_VALUE);          System.out.println("\nLong:");        System.out.println("Long.MIN_VALUE = " + Long.MIN_VALUE);          System.out.println("Long.MAX_VALUE = " + Long.MAX_VALUE);          System.out.println("\n");        System.out.println("\nFloat科学计数法：");        System.out.println("Float.MIN_VALUE = " + Float.MIN_VALUE);          System.out.println("Float.MIN_NORMAL = " + Float.MIN_NORMAL);          System.out.println("Float.MAX_VALUE = " + Float.MAX_VALUE);          System.out.println("Float非科学计数法：");        System.out.printf("Float.MIN_VALUE = %f\n",Float.MIN_VALUE);        System.out.printf("Float.MIN_VALUE = %f\n",Float.MIN_NORMAL);        System.out.printf("Float.MAX_VALUE = %f\n",Float.MAX_VALUE);        System.out.println("\nDouble科学计数法：");        System.out.println("Double.MIN_VALUE = " + Double.MIN_VALUE);        System.out.println("Double.MAX_VALUE = " + Double.MAX_VALUE);          System.out.println("Double非科学计数法：");        System.out.printf("Double.MIN_VALUE = %f\n",Double.MIN_VALUE);        System.out.printf("Double.MAX_VALUE = %f\n",Double.MAX_VALUE);}}

输出结果：
