Write a Java program that reads from the user the 3 points forming a triangle and calculates the triangle’s area in two different methods, using the Heron’s method and the vector method. Be sure to output the result to the user.

Write Java code to read strings of lower-case letters from the keyboard and count the number of vowels in each word. (vowels are a,e,i,o and u). When all strings have been read in, print the string that has the largest number of vowels (duplicates included) and how many vowels were in the string. When more than one string has the greatest number of vowels, print the first string found with that number. For example, with input of she groceries yourselves here radio, the correct answer would be: groceries – 4 vowels.

Write a program that reads integers userNum and divNum as input, and outputs userNum divided by divNum four times.Note: End with a newline. In Java, integer division discards fractions

Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane.  Write a program that reads a string from the keyboard and test whether the string contain any one of these words.  Your program should find words like cAt that differ only in case.   Have your program reject only lines that contain one or more of the three words exactly.  For example, concatenation is a small category should not be considered profane.    This problem can be solved easily.  If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…
