输出:
float max=3.4028235E38
float min=1.4E-45
double max=1.7976931348623157E308
double max=4.9E-324
byte max=127
byte min=-128
char max=?
char min=
short max=32767
short min=-32768
int max=2147483647
int min=-2147483648
long max=9223372036854775807
long min=-9223372036854775808
说明:
实际上是每种类型的Container类定义的常量。
JAVA 各种数值类型最大值和最小值 Int, short, char, long, float,&nbs
