    Here's the code, appreciate who could help me...
    Solved! apparently JAVA doesn't work well with 3 "for" inside each other

    Import java.util.Scanner;
    import java.util.Locale;
    public class ep1 {
     
    	public static void main (String [] args) {
    		Scanner ler = new Scanner (System.in);				
    		ler.useLocale(Locale.ENGLISH);		
    		int nCargos = ler.nextInt();
    		String [] cargo = new String [nCargos];				
    		double [][] peso = new double [nCargos] [14];		
    		for (int i = 0; i < nCargos; i++) {
    			cargo[i] = ler.nextLine();              //I can't read the string if i do not use it twice, idk why also
    			cargo[i] = ler.nextLine(); 			
    			System.out.print (cargo[i] + " : \n");	
    			System.out.println();			
    		for (int u = 0; u < 14; u++) {
    			peso [i] [u] = ler.nextDouble();
    			System.out.printf (peso[i][u] + " ");						
    		  }
    		  System.out.println();
    		  System.out.println("-------------------------------------------------------------");
    	   }
    	   int nPessoas = ler.nextInt();
    	   String [] nome = new String [nPessoas];
    	   double [][] pontos = new double [nPessoas] [14];
    	   double media = 0;
    	   double [] medias = new double [nPessoas];
    	   for (int D = 0; D < nPessoas; D++) {
    		   nome [D] = ler.nextLine(); // Mesmo caso do Scanner nextLine anterior
    		   nome [D] = ler.nextLine();		   
    		   System.out.print (nome[D] + " : \n");
    		   System.out.println();
    		   for (int c = 0; c < 14; c++) {

    	   }
