Follow the steps below to complete the lab$09.$

Open the project for Lab$09$

Add a Java file $($create a class$)$ name it Lab$09$

import java.lang.Math;

Add the main method:

public static main$($String args$[])\{$

$\}$

Reference codes:

a$.$ Equivalent Switch statements and if$-$else statement are shown below:

switch$($operator$)\{$

case $1$:

result $=a+b$;

break;

case $2$:

result $=a-b$;

break;

case $3$:

result $=\frac{a}{b}$;

break;

case $4$:

result $=a^{**}b$;

break;

default:

System.out.print In $("$Invalid operator"$)$;

break;

$\}$

lelse this is equivalent to 'default' in the switch statement

System.out.printIn$($ "Invalid operator"$)$;

$\}$

b$.$ Conditional Operator:

int maxval, x$1=5,$ x$2=10$;

maxval $=($x$1>$ x$2)?$ x$1$ : x$2$;

The above implementation with Conditional Operator is equivalent to $($this is also the algorithm to find the larger between two numbers$)$:

if$($x$1>$ x$2)\{$

maxval $=$ x$1$;

$\}$else $\{$

maxval $=$ x$2$;

$\}$

$6.$ Add codes to the main method to implement the followings with switch statements, logical$,$ relational, and arithmetic expressions.

a$.//$Write the name of the course in a single line comment

b$./*$

Write the course description in a multiline comment

$*/$

c$.$ Print the values of the following variables:

int x $=10$; double y $=5\mathrm{.}0$; float z $=3\mathrm{.}14$f; String course $=$CSCI$1010$L$$;

i$.$ Using println method

ii$.$ Using printf method. Make sure to add new line escape character at the end of the format specifier.

d$.$ Find and print the lower number between the following variables:

int var$1=100$; int var$2=125$;

e$.$ Convert the following if$-$else statements into switch statements:

if$($eqnType $==1)\{$

y $=$ m$*$x $+$ c;

$\}$

else if$($eqnType $==2)\{$

y $=$ a$*$Math$.$pow$($x$,2)+$ b$*$x $+$ c;

$\}$

else if $($eqnType $==3)\{$

y $=$ a$*$Math$.$log$($x$)$;

$\}$

else$\{$

System.out.println$("$Unsupported Equation Type"$)$;

$\}$

Make sure to declare eqnType as int type and all other needed variables as double $($m$,$ a$,$ b$,$ c$,$ x$,$ y$).$ Also, you must initialize them $($except y$).$

f$.$ Use conditional operator to compare the values a and b and to find the larger value and print the larger number.

g$.$ Compare values x and y with $3$ digits of precision and implement the following logic with Condition Operator.

final double TOLERANCE $=0\mathrm{.}001$;

String msg $=""$;

String msg$1=$ "Absolute difference between x & y is less than the Tolerance";

String msg$2=$ "Absolute difference between x & y is not less than the Tolerance";

if $($Math$.$abs$($x $-$ y$)$ TOLERANCE$)\{$

msg $=$ msg$1$;

$\}$else$\{$

msg $=$ msg$2$;

$\}$

System.out.println$($msg$)$;

h$.($Bonus$)$

Use Conditional Operator to Compare the values a$,$ b$,$ and c to find out the largest number. Print the largest number.

$/*$ Following codes implement the problem with if block.

$*$ Find the largest of a$,$ b$,$ c

$*/$

double largest $=$ a;

if $($b $>$ largest$)\{$

x $=$ b;

$\}$

if $($c $>$ largest$)\{$

x $=$ c;

$\}$
