a "filter" function that takes an array (int[]) and returns a new array containing only the non-negative elements of the array.
Write in Java. initializer list example: int [] array = {1,2,3};
dont give the same solution again .10 min left fast Array Indexing: Knowing the basics of array indexing is important for analysing and manipulating the array object. NumPy offers many ways to do array indexing. O slicing: Just like lists in python, NumPy arrays can be sliced. As arrays can be multidimensional, you need to specify a slice for each dimension of the array. O Integer array indexing: In this method, lists are passed for indexing for each dimension. One to one mapping of corresponding elements is done to construct a new arbitrary array. O Boolean array indexing: This method is used when we want to pick elements from array which satisfy some condition
when an individual array element of an array of type int is passed to a method, it is passed by reference. True False
Good-Enough Array Code in C language
Create in Java (1) Create an array of String objects and populate it with the days of the week (7 days)(i.e., Monday - Sunday)(2) Create an array parallel to the one created in (1) to store the entrées. However, you do not have this information, soyou will need to write a loop that prompts the user to enter the entrée served on that day. This prompt shouldinclude the day for which you are asking for the information (e.g., "What entrée is being served on Monday?")(3) Create another parallel array that stores the prices. You will also need to collect this information from the user. Thistime, your prompt should include the name of the entrée for which you are asking for the price(4) Prompt the user to choose an entrée from a list that you display numbered 1 through 7 (have them input a number1 to 7) and search the array and output the day on which the entrée will be served(5) Search through the array for the highest price entrée and output the name of this entrée for the user including…
