Can a class in Java only create one object?

no. In Java, a class can create multiple objects.

Objects in Java are instances of classes. A class defines the data types and behavior of an object, and objects store data values ​​specific to that class. When an object of a class is created, the Java Runtime Environment (JRE) allocates memory to store the object's instance variables.

For example, consider the following class:

<code class="java">class Person {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // ...其他方法
}</code>

We can use this class to create multiple objects:

<code class="java">Person person1 = new Person("John", 25);
Person person2 = new Person("Mary", 30);</code>

These objects are all instances of the Person class , but they are different objects with different data values.

So, in Java, a class can create multiple objects, each of which stores its own set of data values.
