They ask me to do a function in java in which the user passes a vector by parameters and the indexes in which he wants the sum to be made, that is, if I pass any vector t and the indexes 2 and 5 ( sum (t, 2,5)) would have to return the sum of the elements of the vector from index 2 to index 5. The syntax must be the following sum (int [] vecteros, int a, int b) { }
you have to create a cycle that adds up the ranges of the indices, you have to take into account that the indices do not exceed the size of the vector and that a > b in all cases
public class JavaApplication3 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
int [ ] vector = { 2, 7, 4, 7, 15 };
System.out.println(suma(vector, 2,4));
}
public static int suma(int[]vecEnteros, int a , int b){
try{
int suma=0;
for (int i = a; i <= b; i++) {
suma+=vecEnteros[i];
}
return suma;
}catch(ArrayIndexOutOfBoundsException ex){
return 0;
}
}
}
