(4) Modify the code blew fllowing the introduction and prove the full code.

public class Arrays {

public Arrays() {

}

public static void main(String[] args) {

float[][] a = new float[][] {{500, 200}, {100, 400}};

float[] b = new float[] {8, 6};

String[] s = new String[] {"cinema 1", "cinema 2"};

String[] t = new String[] {"Adults", "Children"};

int i,j;

System.out.println(" ");

System.out.println("Cinema Complex Attendance");

System.out.println(" ");

System.out.println(" \t\tAdults\t\t" + "Children");

System.out.println("\t\t_ _ _ _ _ _\t" + "_ _ _ _ _ _ ");

for ( i = 0 ; i <= 1 ; i++ )

{

for ( j = 0 ; j < 1 ; j++ )

System.out.println(s[i] + " \t" + a[i][j] + "\t\t" + a[i][j + 1]);

}

System.out.println(" Cinema Complex Admission ");

for ( i = 0 ; i <= 1 ; i++ )

System.out.println(t[i] + "\t$" + b[i]);

System.out.println(" ");

System.out.println("Cinema Complex Revenue ");

for ( i = 0 ; i <= 1 ; i++ )

{

for ( j = 0 ; j < 1 ; j++ )

System.out.println(s[i] + "\t$" +

(a[i][j] * b[j] + a[i][j + 1] * b[j + 1]));

}

}

}

Output

A movie complex has three separate theaters: Cinema 1 , Cinema 2 and Cinema 3 . The attendance Monday for the entire complex is given in the matrix below.

		Adults	Children
Cinema 1		029	149
Cinema 2		059	043
Cinema 3		147	011

If the admission price for each cinema is $ 4 for children and $ 8 for adults, find the total revenue that was collected Monday at the theater complex.

Output

Also,

Provide comments statements for each line of the Java Code shown below (i.e., give the lines purpose).

public class CharacterInfo

{

public static void main(String[] args)

{

char aChar = 'C';

System.out.println("The character is " +aChar);

if(Character.isUpperCase(aChar))

System.out.println(aChar + " is uppercase");

else

System.out.println(aChar + " is not uppercase");

if(Character.isLowerCase(aChar))

System.out.println(aChar + " is lowercase");

else

System.out.println(aChar + " is not lowercase");

aChar=Character.toLowerCase(aChar);

System.out.println("After toLowerCase(), aChar is " + aChar);

aChar=Character.toUpperCase(aChar);

System.out.println("After toUpperCase(), aChar is " + aChar);

if(Character.isLetterOrDigit(aChar))

System.out.println(aChar + " is a letter or digit");

else

System.out.println(aChar + " is neither a letter nor a digit");

if(Character.isWhitespace(aChar))

System.out.println(aChar + " is whitespace");

else

System.out.println(aChar + " is notwhitespace");

}

}

finally please Create a flow chart for the above code.

Thank you very much
