1) What is the value of
amt
for each of the expressions below? Note the type declarations for each. To represent
an integer value, do not write a decimal point (for example: 99 or 42). To represent a double value, write a
decimal point and one digit to the right of the decimal point (for example: 99.0 or 42.5).
int amt = 10;
amt = amt + amt * (5 / 100); ____________
int amt = 10;
amt = (int) (amt + amt * (5 / 100.0)); ____________
double amt = 10;
amt = amt + amt * (5 / 100); ____________
double amt = 10;
amt = amt + amt * (5 / 100.0); ____________

loc1 == loc2 ______________
loc1 == loc3 ______________
loc2.equals( loc1 ) ______________
loc3.equals( loc1 ) ______________
