I am new to Java programming, I want to create are multiple numbers of strings, for that I written the code below. Why does it generate same hash code for both string objects?

        }
        public class SingletonObjectDemo {

                String str = SingletonClass.mystring;
                String str2 = SingletonClass.mystring;
                System.out.println("String str  "+str.hashCode());
                System.out.println("String str1  "+str2.hashCode());
                    }
        }

推荐答案

它正在为两个字符串对象生成相同的哈希码...因为它们是同一对象.
