Section 4.3.3 Check Point Questions5 questions 

Use print statements to find out the ASCII code for '1', 'A', 'B', 'a', and 'b'. Use print statements to find out the character for the decimal codes 40, 59, 79, 85, and 90. Use print statements to find out the character for the hexadecimal code 40, 5A, 71, 72, and 7A.

Evaluate the following:

int i = '1';
int j = '1' + '2' * ('4' - '3') + 'b' / 'a';
int k = 'a';
char c = 90;

Can the following conversions involving casting be allowed? If so, find the converted result.

char c = 'A';
int i = (int)c;

float f = 1000.34f;
int i = (int)f;

double d = 1000.34;
int i = (int)d;

int i = 97;
char c = (char)i;

Show the output of the following program:

public class Test {
  public static void main(String[] args) {
    char x = 'a';
    char y = 'c';

    System.out.println(++x);
    System.out.println(y++);
    System.out.println(x - y);
  }
}

Write the code that generates a random lowercase letter.
