calculation error problem, but also saves the programming memory to allocate the trouble.5, we put the keyword in the Java program before the method name, to implement the subclass calls the parent class method.Four, simple answer (5 points per question * 4 = 20 points)1. What are the similarities and differences between abstract class and interface (interface)?2. What is a Java virtual machine? Why is Java called a "platform-agnostic programming language"?3, explain the difference between over

String, shaping, floating-point, tuple elements (characters) of the index is immutable, cannot change is that you can use the variable name with square brackets, and then filled in square brackets inside the index value of the string, the index value is zero-based, and the list of words inside the element index value can be arbitrarily assigned valueWhen the slice has a step, the opening end is contained within it and is intercepted. But what if the slices have no stride size? The beginning cont

First, the topic requirements1.1 Enter an array of integers with positive numbers in the array and negative values. 1.2 contiguous one or more integers in an array make up a sub-array, each of which has a and. 1.3 If the array a[0] ... A[j-1] next to each other, allowing a[i-1], ... A[n-1], a[0] ... A[J-1] and the largest. 1.4 Returns the position of the largest sub-array at the same time. 1.5 The maximum value of the and of all sub-arrays is evaluated. Requires a time complexity of O (n).Second
