Write a program in Java to implement the min-priority queue using min-heap data structure. Implement the min-heap data structure using a String array of 5 cells. (Do not use Java in-built PriorityQueue class.) [In a min-heap, the root node and the intermediate node vales are always smaller than their children.] First, take 5 names from the user and insert them in the min-priority queue. Then print the elements of the queue. After that, delete two elements from the queue and...

You are to write a Java program that reads an input file containing a list of words and their synonyms. You will repeatedly ask the user if they want to look up the synonyms of a word, add a new synonym for a word, or quit. Here is a sample run of the program (note that the program is expecting the input file, thesaurus.txt to be in the working directory for the code.): Enter...

Write a Java program in Eclipse. . Write a Java program that: 1. Creates an array of 100 integers. Initialize the array to have all zeros. 2. Puts even numbers starting from 6 (excluding multiples of 12) into the first 50 slots of the array above. So numbers 6,8,10,14,16,18,20,22,26, etc. go into the first 50 positions in the array. Print the array. 3. Puts random numbers between 45 and 55 into the second 50 slots of the array above (second...

Write a Java program that prompts the user to enter an integer and determines whether 1. it is divisible by 5 and 6, whether on 2. it is divisible by 5 or 6, 3. it is divisible by 5 or 6, but not both. Here is a sample run of this program: Sample run: Enter an integer: 10 Is 10 divisible by 5 and 6? false Is 10 divisible by 5 or...
Write a java program that demonstrates recursion. This program can be in a java GUI frame or as a console application. On this one it is up to you. (It would probably work better as a console program for this particular program.) The input for this program is a number of boxes. Ask the user for this with a textbox or a prompt on the command line. Demonstrate recursion with a function called LoadTruck() that takes a number of boxes...
Java Submit a program in a .java file. The program should print a multiplication table for the numbers 1-9. This requires a nested for loop. The outer loop moves from row to row, while the inner loop prints the row. Use tabs to separate the output, such as in the following statement: System.out.println(“1\t2\t3\t4\t5\t6\t7\t8\t9”); Output should look similar to the following. 1 2 3 4 5 6 7 8 9 ------------------------------------------------------------------ 1 2 3 4 5 6 7 8 9...
