Assignment3

1. Rewrite the following set of if statements using a nested if-else structure.
if (score = 90) grade = 'A';
if (score = 80 && score < 90) grade = 'B';
if (score = 70 && score < 80) grade = 'C';
if (score = 60 && score < 70) grade = 'D';
if (score < 60) grade = 'F';
2. Rewrite the following nested if-else statement as an equivalent switch statement.
if (letter == 'A' | | letter == 'a')
System.out.println("Excellent");
else if (letter == 'B' | | letter == 'b')
System.out.println("You can do better");
else if (letter == 'C' | | letter == 'c')
System.out.println("Try harder");
else if (letter == 'D' | | letter == 'd')
System.out.println("Try much harder");
else
System.out.println("Try another major! ");
Write a program called Assignment3 (saved in a file Assignment3 .java) that asks a user to enter
two strings.
First, the program prompts:
Please enter a string.
The program should read in the string, and prompts:
Please enter another string.
The program reads in the string and performs the following:
 checks if each string's length is odd or even.
 checks if two strings are same or different.
 checks which string is lexically larger, or they are same.
 prints out the first character (index 0) of each string
 prints out a new string consisting of the first string concatenated (appended) with the
second string.
 prints out two strings using upper case letters.
Here is the output your program should produce when the user enters the string shown in bold:
