In java, how can I create an array inside an array of different data types [duplicate]

You can't do that by specifying the types of the arrays, one solution can be is to create a class called Cabin

public class Cabin {
    private String name;
    private int capacity;
    private double peak;
    private double offBeak;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getCapacity() {
        return capacity;
    }

    public void setCapacity(int capacity) {
        this.capacity = capacity;
    }

    public double getPeak() {
        return peak;
    }

    public void setPeak(double peak) {
        this.peak = peak;
    }

    public double getOffBeak() {
        return offBeak;
    }

    public void setOffBeak(double offBeak) {
        this.offBeak = offBeak;
    }
}

And then create an array of Cabin

    Cabin[] cabins = new Cabin[3];
    Cabin cabin = new Cabin();
    cabin.setName("Hetty");
    cabin.setPeak(4);
    cabin.setOffBeak(250.00);
    cabins[0] = cabin;

You can achieve it by creating the outer array of type Object

        Object[] genericArray = {cabin_names, cabin_capacity, cabin_peak, cabin_offpeak};
