• The name of the user-defined method seen in the code below is minFunction.

  
• The VOID keyword is used in Java user-defined methods to denote that it does not return any value to the main method
• In Java, parameters are passed to arguments via a function call
• It is not possible in Java to write code with more than one user-defined method in it false
• To avoid a syntax or runtime error, change sum to double datatype
• The code snippet would not produce an error when executed
• The Java user-defined method shown in the sample code has two arguments
• It is possible for a Java user-defined method to accept more than a single argument true
• The name of the Java class seen in the code is udmSample
• Standard arrays can hold data items of the same data type, so an array is a homogeneous data structure
• A single-dimensional array (1D array) only has columns of data items true
• An array is also called an index (a subscript) / subscripted variable
• The preferred method for creating an array in Java is dataType[] arrayRefVar;
• A 3x4 2D array has 3 rows and 4 columns, so it can store 12 data items
• A 2D array (two-dimensional array) has both rows and columns of data true
• What is the value of arr11[1] after the following code snippet is execute?

  int[] arr11 = {1, 2, 3};

  arr11 = Arrays.copyOf(arr11, arr11.length + 1); arr11[3] = 4;

  2
• The statement int[] arr4 = new int[10]; creates a new array of integers with 10 elements, all initialized to 0
• The given code snippet

  int[] arr2 = new int[3];

  arr2[0]

  arr2[1]

  arr2[2]

  creates a new array of integers with 3 elements and assigns values to each element
• The output of the given code snippet

  int[] arr1 = {1, 2, 3, 4, 5};

  System.out.println(arr1[4]);

  is 5
• The value of arr8[2] after the given code snippet is executed

  int[] arr8 = {1, 2, 3, 4, 5};

  int[] temp = arr8;

  temp[2] - 10;

  is 3
• The value stored in the first element of arr2 is 0
• The given code snippet

  int[] arr9 = (1, 2, 3, 4, 5);

  for (int i = 0; i < arr9.length / 2; i++) {

  int temp arr9[1];

  arr9[i] = arr9[arr9.length-1- i]

  arr9[arr9.length - 1 i]= temp;

  }

  reverses the elements in the array arr9
• The output of the given code snippet

  int[] arr6 = {1, 2, 3, 4, 5};

  int[] arr7 = new int[arr6.length];

  for (int i = 0; i < arr.length; i++)

  { arr7[i] = arr6[arr6.length-1- i];

  }

  System.out.println(arr7[2]);

  is 3
• The method Arrays.sort(arr2) sorts the elements of the array arr2 in ascending order
• The value of arr3.length after the given code snippet is executed

  int[] arr3 (10, 20, 30, 40);

  arr3[2] = 50;

  is 4
• The length of the array arr1 is arr1.length
• The output of the given code snippet is 10

  int[] arr10 = {1, 2, 3, 4, 5};

  int sum = 0;

  for (int i = 0; i < arr10.length; i++) { sum += arr10[1];

  }

  System.out.println(sum);
• Arrays are usually processed in sequential fashion and therefore loops are used to repetitively access its values and perform operations on these values true
• The preferred method for declaring an array in Java is dataType[] arrayRefVar true
• In Java, an array with a maximum size of ten (10) data items would have indexes 0-9
