  1. Sorting and Searching Arrays

  2. Partially Filled Arrays • Not all elements of the array might receive values: • This is termed a partially filled array. • Programmer must keep track of how much of array is used.

  3. Consider arranging elements of an array so that they have an ascending order. • Algorithm is to step through the array: • Place the smallest element in index 0. • Swap elements as needed to sort the entire array.

  4. This method sorts the array This method searches for the next smallest element

  5. “selectionSort (arg)” is a static method ClassName . staticMethodName (arg)

  6. MultidimensionalArray we can access elements of the table with a nested“for” loop

  7. column 0 1 2 3 4 5 5 5.5 6 6.5 7 7.5 declaring a 2-dimentional array year 1 2 3 4 5 6 7 8 9 10 computing the contents of the array printing the contents of the array

  8. using System.out.println(…); using 2 “for” loops and System.out.println(…);
