Helps In Java Please

السلام عليكــم ورحمـة الله وبركاتــة ،،

لو سمحتوا اخواني محتاجه مساعدة فحل هالمسائل باستخدام برنامج الاكلبس او الجافا

بليز محتاجة الحل ضروري

1- converting an uppercase to lower case ,write a method that converts an uppercase letters to a lowercase letters .Use the following method header:

public static char UppercaseToLowerCase(char ch)

the offset between any uppercase letters and its corresponding lowercase letters is the same.So we can use the following:

int offset = (int)'a' - (int)'A';

char lowercase = (char)((int)uppercase+offset);

2-(summing the digits in an integer)Write a method that computes the sum of the digits in an integer . use the following method header:

public static int sumDigits(long n)

for example;sumDigits(234)return 2+3+4=9.

3-(Display an integer reversed)write the following method to display an integer in reverse order:

public static void reverse(int number)

for example ,reverse (3456)display

6543.

4-(Return an integer reversed)write the following method to return an integer in reverse order:

public static int reverse(int number)

for example ,reverse (3456)return

6543.

5- (Sorting three nuumbers)write the following method to display three numbers in increasing order:

public static void sort(double num1,double num2,double num3)

6-(Displaying matrix of 0s and 1s)write amethod that displays an n by n matrix using the following header:

public static void printMatrix(int n)

each element is 0 oor 1, which has generated randomly .Write a test program that prints a 3 by 3 matrix that may look like this:

0 1 0

0 0 0

1 1 1
