Given the following Java code that is embedded in a correct program:

System.out.print$($Enter a number: $)$;

num $=$ scan.nextInt;

switch $($num$)$

$\{$

case $1$:

System.out.print$($New York$)$;

break;

case $2$:

System.out.print$($San$)$;

case $3$:

System.out.print$($Francisco$)$;

break;

default:

System.out.print$($Chicago$)$;

$\}$

What is the output if the user enters $3?$

What is the output if the user enters $2$

What is the output if the user enters $0?$

Given a String str and a char aChar both of which already have values, write Java code that prints "Yes" if aChar is contained in str and $"$No$"$ otherwise.
