3. Sort elements using String ArrayList Example Sort the array elements order by A-Z Input: Array={“Arun”,”sector”,”checking”,”merge”,”define”,”generate”} 4.Take a string and use “ Collection” concept and print the results Example Given input some word? EX: Input: TESTINGFILE Print the output collection? EX: Output: FIGTTSEEINI

5.Write a program to reverse the string Without using String API Example: Input: MERGECLOSER Output: RESOLCEGREM 6. array= {1,9,8,3,7,6,8,9,4,2,5,7,8,9,6,5,2,4,7,3,1,8,2,9} Calculate the array size? Find the repeated character with count? Find the largest number in array?

7. Write a program to check if a 3 digit number is Armstrong number and print “Yes “ if it is Armstrong number and “No” If it is not an Armstrong number. Hint: An Armstrong number of 3 digit is a number for which sum of cube of its digits are equal to number e.g. 371 is an Armstrong number because 3*3*3 + 7*7*7 + 1*1*1 = 371). 8.Write a program to Print Even and Odd No. Repeatedly using two Threads in Java ?

9. Print following text using “constructor chaining” with different parameter. a.In default constructor... b. In single parameter constructor... c. In double parameter constructor... Note: (Use 3 constructor and work out the logic)
