Write a Java program to find nth Catlan number. Try to give the highly Optimised Code and code should take input from the user.

Check which is larger 0.0 or minimum value of double and also verify this in java

in Java Read the input line one at a time. If you read less than 200 lines output nothing. If you read less than 500 lines then output the 200th line in sorted order of the input lines. If you read more than 1000 or more lines, then only consider the last 1000 lines, and output the 200th line in sorted order from the last 1000 lines. Do not store more than 1001 lines.

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

Write a Java program that will use while loops. The while loop will show the cards currently in the hand and ask the user to accept a card (Hit) or to stop (Stand). Within the while loop the program should print the card that was just added, all the cards in the hand, and the new value of the hand. If the value of the hand exceeds 21, the game should end (the while loop should stop). Write out the algorithm for the while loop. Turn in a printout of the algorithm, the code and a printout of a sample run. Place the algorithm and the sample run inside comment blocks in the code. "The sample runs of such a program are on the attached image."

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

Write a Java program to take nth number from the user. So your code have to print the Fibonacci Number using Iteration. You have to handle all the base cases in your code

in java, check correct input with try block and extension

JAVA Write a java program that takes a string as input from the user and finds out if the string is a palindrome or not. A string is a palindrome if it reads the same from forward as well as from backward. For example, the string "madam" is a palindrome. Use a for loop to solve this problem. Sample inputs and outputs: Input: madam Output: palindrome Input: Dad Output: palindrome Input: hello Output: not a palindrome
