I found only the class Runtime , but it returns only values in numbers, such as total memory and processors. Is there any API that returns hardware data (processor version, RAM, architecture, etc.) as in CCleaner?

I use the SIGAR basically does what you asked for: Documentation

After downloading SAGAR API.Jar and including it in the compilation path, here is an example of use:

import java.io.*;
import java.util.*;
import java.text.*;
import java.lang.*;

import org.hyperic.sigar.Mem;
import org.hyperic.sigar.Sigar;
import org.hyperic.sigar.SigarException;

public class MemExample {
    private static Sigar sigar = new Sigar();

    public static void getInformationsAboutMemory() {
        System.out.println("**************************************");
        System.out.println("*** Informations about the Memory: ***");
        System.out.println("**************************************\n");

        Mem mem = null;
        try {
            mem = sigar.getMem();
        } catch (SigarException se) {
            se.printStackTrace();
        }

        System.out.println("Actual total free system memory: " + mem.getActualFree() / 1024 / 1024 + " MB");
        System.out.println("Actual total used system memory: " + mem.getActualUsed() / 1024 / 1024 + " MB");
        System.out.println("Total free system memory ......: " + mem.getFree() / 1024 / 1024 + " MB");
        System.out.println("System Random Access Memory....: " + mem.getRam() + " MB");
        System.out.println("Total system memory............: " + mem.getTotal() / 1024 / 1024 + " MB");
        System.out.println("Total used system memory.......: " + mem.getUsed() / 1024 / 1024 + " MB");

        System.out.println("\n**************************************\n");

    }

    public static void main(String[] args) throws Exception {
        getInformationsAboutMemory();
    }

}
