String Manipulation and Palindrome-Anagram Exercises
Praktikum PBO
String
Soal 1
•
Buatlah program untuk menghitung jumlah
huruf dan angka dalam sebuah kalimat
•
Kalimat : Keputih 78 A
•
Jumlah huruf : 8
•
Jumlah angka : 2
Soal 2
•
Write a program that reads a string and then prints a diamond shaped
array based on the characters of the string. As an example, if the string has
the value "SAMPLE", then the program should print the pattern
S
SAS
SAMAS
SAMPMAS
SAMPLPMAS
SAMPLELPMAS
SAMPLPMAS

A palindrome is a string that reads the same both forward and backward.
Examples of palindromes are
"radar"
and
"31413".
(a) Write a boolean-valued method isPalindrome that has a single String
parameter. The method should return true if and only if its parameter is a
palindrome.
(b) Modify your method so that it ignores cases of letters, punctuation marks,
and blanks in making a decision about whether or not a string is a
palindrome. For
example, the string:
"A man, a plan, a canal: Panama!"
should be taken to be a palindrome.
Write a program that prompts the user for a string and notifies the user if it is
apalindrome.

Exercise: An anagram is a word or a phrase
made by transposing the letters of another
word or phrase; for example, "parliament" is
an anagram of "partial men," and "software"
is an anagram of "swear oft." Write a program
that figures out whether one string is an
anagram of another string. The program
should ignore white space and punctuation.
