3. Explain your answers. 8. 3. Explain your answers. 9. 3. Explain your answers. 2 Sorting: Insertion Sort Sorting algorithms are an important family of computational algorithms. An array of items named data with length n is called sorted if for all i < n − 1, data[i] <= data[i+1] Such an array is called nondecreasing; nonincreasing is defined similarly. Insertion Sort Insertion sort is often used by card players to sort their hands. The idea is to view the data in two sections: the left section is a sorted subset of the data, while the right section contains items that remain to be sorted.

FieldName references a field rather than some other variable such as a parameter or local variable. 5, this allows the parameters of the constructor to have the same names as the fields, instead of requiring the programmer to choose different names for the parameters. num on the left refers to the field named num, whereas num on the right refers to the parameter. This is generally the only time we reuse field names; otherwise, there is a danger that the fields will be hidden by local variables or parameters.

4 matches any string of one or more characters of whitespace (spaces, tabs, or newlines). It works like this: the pattern “ \s” matches any single whitespace character. But to use the pattern “ \s” in a string literal (as here), the backslash must be escaped with another backslash; thus the string literal pattern "\\s" matches any one character of whitespace. Appending a “ +” to a pattern matches one or more occurrences of the pattern, and so, "\\s+" matches any set of one or more characters of whitespace.
