the length of array_a : 1
the length of array_b : 1

a[0] = 70	b[0] = 70
The array_a only has one element.
So the max value of array_a is same as the min value!

the length of array_a : 7
the length of array_b : 7

a[0] = 39	b[0] = 39
a[1] = 90	b[1] = 90
a[2] = 49	b[2] = 49
a[3] = 35	b[3] = 35
a[4] = 33	b[4] = 33
a[5] = 12	b[5] = 12
a[6] = 75	b[6] = 75

The max value of array_a is : 90
The min value of array_a is : 12

the length of array_a : 0
Exception in thread "main" the length of array_b : 0

java.lang.ArrayIndexOutOfBoundsException: 0
