Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Consider the following Java method.
void modifyDNA ( String dna) {
int [] frequency = { 0, 0, 0, 0, 0 };
for (int i = 0; i < dna. length (); i++) {
switch (dna.charAt (i)) {
case 'A':
frequency [0]++; ngular Snip
break ;
case 'T':
frequency [1]]++;
case 'C':
frequency [2]++;
break ;
case 'G':
frequency [3]++;
default :
frequency [4]++;
}
// HERE
}
If the method is called as follows, what is the expected values of the array elements when the
execution reaches the comment line // HERE , when the method is executed with the parameter
value "ATCGGT" ?
O [1,2,1,2,2]
O [1,2,3,2,2]
O [1,2,3,2,0]

FOR JAVA, with StdDraw, and StdRandom Write a static method histogram() that takes an array a[ ] of int values and an integer M as arguments and returns an array of length M whose ith entry is the number of times the integer i appeared in the argument array.

Java please, Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1 Hint: Use two arrays, one for the strings, another for the frequencies. Your program must define and call a method:public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord) Note: This is a lab from a previous chapter that now requires the use of a method.

Beginner Java import java.util.Arrays;import java.util.Scanner; Arrays and scanner required. Suppose that a Scanner object contains a bunch of tokens all on a single line separated by spaces. For example: 100.5 65 pizza 100 45.75 70 5.8 5 Also suppose that you have two integers n and m that are both positive. For example: n = 5 and m = 10 Write a static method: public static double partialSum(Scanner s, int n, int m) that takes a Scanner and two integers n and m as arguments and returns the sum of the integers read by the Scanner that are divisible by n and not divisible by m. In the above example, the integers divisible by 5 and not divisible by 10 are 65 and 5, so the result would be 70. If the Scanner is empty, or no tokens are valid integers, the result should be 0. You can assume the Scanner is not null. It is probably easiest to test your method by creating a Scanner with a String instead of System.in. The starter code for an example of how to do this is…
Write a Java method named addArray which takes two arrays of same size as parameters. The method should return a third array that is the element-wise sum of the two arrays. For example, if the two input arrays are [1,2,3] and [4,5,6], then the returned array should be [5, 7, 9]. [ 1, 2, 3] + [ 4, 5, 6] = [1+4, 2+5, 3+6] = [5,7,9] Call addArray in main method to test the above example. Print the returned array in the main method. Write a JAVA code please
Write a Java program to find continuous sub array of the given array whose sum is equal to a given number. For example, If {12, 5, 31, 9, 21, 8} is the given array and 45 is the given number, then you have to find continuous sub array in this array such that whose elements add up to 45. In this case, {5, 31, 9} is such sub array whose elements add up to 45.
