Flexible Constructors

Java 23 will loosen restrictions on how the super() method will be called. It need not be called the first operation in the derived constructor.

Initialize Fields
- The super call to the Base Classes constructor will be permitted after initializing the variables.

String value;

public Constructor(String aValue) {
	value = aValue
	super()
}

Call Static Methods
- Additionally, the super call will also be permitted after a static method

public Constructor(String aValue) {
	value = aValue;
	check(value)
	super()
}

public static void check(value) {
	...
}

Create local variables
- The super can now also accept local variables that have been modified prior to its call

public Constructor(String aValue) {
	var value = aValue * 2;
	super(value,value)
}

The reason the changes above were made was so as to allow both
