bueno aca le dejo el primer ejercicio propuesto corregido lo hice asi sencillo si alguna duda pueden consultarme
import java.io.*;
public class suam{ public static void main (String[] args) {
int n1=50,n2=30,suma=0,n3=0;
suma=n1+n2;
System.out.println("la suma es:"+suma);
suma=suma+n3;
System.out.println("su otra suma es:"+suma);
} }
aca le dejo otro de suma pero esta vez esta iterativo y recursivo para que vean la diferencia ambos arrojan los mismo resultado
import java.io.*;
class sum{ BufferedReader lei=new BufferedReader (new InputStreamReader(System.in)); int sumari(int i)throws Exception{ if (i==5) return (i); else return (sumari(i+1)+i); } void mostrar(int i) throws Exception{ if (sumari(i)>5){ System.out.println(sumari(i)); } } void iterar() throws Exception{ int i,p=0; for(i=0;i<=5;i++){ p=p+i; } System.out.println(p); }
}
public class sumar { public static void main (String[] args) throws Exception {
int i=0;
sum sumao = new sum();
sumao.sumari(i); sumao.mostrar(i); sumao.iterar(); } }
