Enter mortgage term (1, 2, 3, 5, 10): 1
Enter mortgage amortization period (5, 10, 15, 20, 25): 30
30 is an invalid amortization period
Enter mortgage amortization period (5, 10, 15, 20, 25): 25

Can you explain what we need to do in this ?

Answer 2

import java.util.Scanner;
public class Program{
public static void main(String[] args){
int validTerms[]={1,2,3,5,10};
int validPeriod[]={5,10,15,20,25};

//for taking term & period as input from user
Scanner sc=new Scanner(System.in);
int term=sc.nextInt();
int period=sc.nextInt();

if(check(validTerms, term)){
//now need to check Period
if(check(validPeriod, period)){
System.out.print("you entered valid montgage term & amortization period");
}
else{
System.out.print("enter valid amortization period" );
}
}
else{
System.out.print ("enter valid montgage term");
}
}

//method for checking term or period is valid or not
static boolean check(int array[],int n){
for(int a:array){
if(n==a) return true;
}
return false;
}
}

looks correcrt function(you can write its starting letter with small, and you need to add 1 return statement more as return type is int) but in SL we can take whole input only 1 time only

Answer 4

I readed about mortgage term & amortization period but still don't understand what you want to do in this ?

if I understand correctly, you only want to take 2 inputs, one for mortage term & another for amortization period, and then check if they are available in set of values specified for them respectively ?
if that is the case then you need to make 2 array for valid values of mortgage terms & amortization period , then take 2 integer inputs(one for mortgage term & another for amortization period) and store them in 2 different variables, and for checking them you can use if() statements along with || operator and == operator.

Welcome ☺
//I thought something related to economics here

Answer 6

source above but in loop:

public class Program {
static Scanner sc=new Scanner(System.in);

static int EnterInt (String msg, int values[]){
int n;

while (true) {
System.out.println(msg);
n = sc.nextInt();
if (check(values, n) )
return n;
else
System.out.println("Incorrect value "+n);
}
}

//... main()

Answer 7

System.out.print(“Enter mortgage term in years (1, 2, 3, 5, 10): “
If i enter “7” as the output it should say “7 is an invalid term, please re-enter.”
because it is invalid it will then ask again to “Enter mortgage term in years (1, 2, 3, 5, 10): “ and if I put 1 for example it will then stop asking that question and ask a new question which is “Enter mortgage amortization period (5, 10, 15, 20, 25): “

Answer 8

yes exactly i am using if statements along with || and == operator but how do i loop the question to ask again once i put an output that is not valid?

Answer 9

Thank you very much. I truly appreciate it.

Answer 10

do i use do-while loop to get two different outputs for mortage term and amortization period?
