In principle 2:Java, as long as you use the new keyword to create an object, a new object must be created (in the stack or stack area).

Principle 3: if you create a String object using direct assignment or using pure string concatenation, you will only check the strings in the maintenance String pool, and there is no one in the pool. But the String object will never be created again in the stack area.

Principle 4: using an expression that contains variables to create a String object not only checks to maintain the String pool, but also creates a String object in the stack area.
