1 /*2 * Write Java applications as required. (1) Create a class called a motor vehicle:3 * Properties: Vehicle grade (String), speed (int), load capacity (double)4 * Function: Speed up (auto increase), deceleration (speed reduction), modify the license plate number, check the load capacity of the vehicle. 5 * Write two construction methods: a non-formal parameter, in the method of the license plate number Set "XX1234", Speed6 * The degree is set to 100, the load weight is set to 100, and the other can assign values to all properties of the object;7 * (2) Create a main class: Create two motor vehicle objects in the main class. 8 * When creating the first call to the parameterless constructor method, call the member method to make its license plate "Liao A9752" and let it accelerate. 9 * Create a second time call parameters of the construction method, so that its license plate is "Liao B5086", the speed of 150, the load is ten,Ten * And let it slow down.
