package exercicio5;
import java.util.*;
public class Exercicio5 {
public static void main(String[] args) {
int i,n1,x;
Scanner ler;
ler = new Scanner(System.in);
for(i=1;i<=10;i++){
x=n1*i;
System.out.println("Digite o 1°número" +n1);
n1 = ler.nextInt();
System.out.println("Multiplicação de 1 até 10" +x);
}
}
}
Is making a mistake in: x=n1*i;

The error is that not initializing the variable to use it, initiating would solve the problem. But this code can be simplified and the variable is not necessary, even there was a logic error making account before the moment you can do and printing wrong information about which number you are typing. Organizing better and using a pattern closer to what people do:
package exercicio5;
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner ler = new Scanner(System.in);
for (int i = 0; i < 10; i++) {
System.out.println("Digite o 1°numero" + i);
int n = ler.nextInt();
System.out.println("Multiplicação de 1 até 10" + n * i);
}
}
}
Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
package exercicio5; import java.util.; public class Exercicio5 { public Static void main(String[] args) { int i,n = 0,x; Scanner read; read = new Scanner(System.in); System.out.println("Enter number" +n); n = read.nextInt(); for(i=1;i<=10;i++){ x=ni; System.out.println("Multiplication from 1 to 10 " +x); } } } 1,n2,n*3 etc...
is still wrong and disorganized
