Hello im new to java and in my class my prof wants us to create a program that will compute the sum of two numbers. (Use methods) For example: Input an integer: 95 //Expected Output: The sum is 14 //(9+5=14)
im really lost on this one because i really don't know how to do this please help
From an algorithm point of view, the easiest way would be to:
In "Modern" java:
String.valueOf(test).chars().mapToLong(c -> Long.parseLong("" + (char) c)).reduce(Long::sum).getAsLong()
In older java:
int test = 95;
long sum = 0;
for (char c : String.valueOf(test).toCharArray()) {
sum += Integer.parseInt(String.valueOf(c));
}
System.out.println(sum);
In javascript:
let sum = 0
for (let c of String(test)) {
sum += parseInt(c)
}
console.log(sum)
If you use Java you can use this code:
int num = 95;
int sum = 0;
while (0 != num) {
// add the last digit of the given number to the sum
sum = sum + (num % 10);
// remove the last digit of the given number
num = num / 10;
}
System.out.println(sum);
(The code in JavaScript is very similar)
