Hello everyone, right now I'm taking a java class, and I'm having one error in my app.
Right now I have to .java files, one which calls the methods from another .java file.
When I compile the first java file, it doesn't give me any error. But when compiling the 2nd one, Jgrasp gives me the following error.
UsaArreglos.java:80: existeValor(int[],int,boolean) in Arreglos cannot be applied to (int[])
x2 = Arreglos.existeValor(a);
^
1 error
The first java file (which stores the methods) is the following
import javax.swing.*;
public class Arreglos {
int valor;
// Metodo 1
public static void inicializa1(int a[]) {
for (int i=0; i<a.length; i++) {
a[i] = (int)(Math.random() * 999);
}
}
public static void inicializaTeclado (int a[]) {
for (int i=0; i<a.length ; i++){
a[i]=Integer.parseInt(JOptionPane.showInputDialog(null, "Teclea el valor de a["+i+"]","Leer Arreglo",-1));
}
}
public static void inicializa2 (int a[]){
int[] a0;
int x = Integer.parseInt(JOptionPane.showInputDialog(null, "Tecle los arreglos que quiere ver : ","Leer Arreglo",-1));
a0 = new int [x];
for (int i=0; i<=a0.length ; i++){
a[i] = i;
}
String s;
s = "";
for (int i = 0; i<a0.length; i++)
// Contatenar l contenido de a a s
s = s + "a[" + i + "]=" + a[i]+"\n";
//despliegar GUI
JOptionPane.showMessageDialog (null,s,"Desplegar", -1);
}
public static void inicializa3 (int a[]){
for (int i = 0; i<a.length; i++){
int x0 = i * 2;
a[i] = x0;
}
}
public static void inicializa4 (int a[]){

}
public static void inicializa5 (int a[]){
int x0 = 1;

}
}
//Metodo que encuentra l valor Maximo del arreglo
// Inicializa el mayor integer.min_value
public static int elMayor (int a[]){
int mayor = Integer.MIN_VALUE;
for (int i=0; i<a.length ; i++){
if (mayor < a[i]) {
mayor = a[i];
}
}
//returnar el mayor
return mayor;
}
public static int elMenor (int a[]){
int menor = Integer.MAX_VALUE;
for (int i=0; i<a.length ; i++){

menor = a[i];
}
}
//returnar el menor
return menor;
}
public static int laSuma (int a[]){
int suma;
suma = 0;
for (int i =0; i<a.length ; i++){
suma = suma + a[i];
}
return suma;
}
public static double promedio (int a[]){
double suma;
double promedio;
suma =0;
for (int i = 0; i<a.length ; i++){
suma = suma + a[i];
}

return promedio;
}
public static boolean existeValor (int a[], int valor, boolean v){
v = false;
int i = 0;
JOptionPane.showInputDialog(null,valor,"Inserte un Valor",-1);
while (v = false || a.length > i ){
if (a[i]== valor){
v = true;
}
else
i++;
}
return v;
}
//Despliega el contenido
public static void despliega(int a[]) {
String s;
s = "";
for (int i = 0; i<a.length; i++)
// Contatenar l contenido de a a s
s = s + "a[" + i + "]=" + a[i]+"\n";
//despliegar GUI
JOptionPane.showMessageDialog (null,s,"Desplegar", -1);
}
}
and then I have the next java file, which calls the methods
