Without show your code we can't help.

Answer 2

int aleatorio;
int matriz[][] = new int[3][3];
int f,c;

for(f = 0; f < matriz.length; f++){
for(c = 0; c < matriz.length; c++){
aleatorio = (int)((Math.random()*75)+1);

while(aleatorio != matriz[f][c]){
if(aleatorio == matriz[f][c]){
matriz[f][c] = aleatorio = (int)((Math.random()*75)+1);
}
else{
matriz[f][c ] = matriz[f][c];
}
}
}
}

for(f = 0; f < matriz.length; f++){
for(c = 0; c < matriz.length; c++){
System.out.print("[ " + matriz[f][c] + " ]");
}
System.out.println("");
}
