PART 3 of other question I asked this question is different Advanced Programming Languages This is a disscussion topic please go into detail one consequence of scope rules in most languages is that forward references (referring to names before they are declared) are prohibited. Are such forward references always prohibited within a single Java class? Are forward references of local names always prohibited within a single method? If not, provide an example that demonstrates your claim. Question and instructions: One consequence of scope rules in most languages is that forward references (referring to names before they are declared) are prohibited. Are such forward references always prohibited within a single Java class? Are forward references of local names always prohibited within a single method? If not, provide an example that demonstrates your claim. **** please don't just copy something off the internet and answer the question. This has to be in your own words and not a novel copied from a website or document. (The teacher also has access to the internet sites your copying from)

Explanation / Answer

Forward Reference implies attempting to utilize a strategy or Variable before its characterized in code part.

Java allows Forward Reference not at all like C or C++ in which we need to proclaim a model of Methods before fundamental() to utilize it.

Utilization of class variables whose announcements show up literarily after the utilization is now and again limited, despite the fact that these class variables are in extension . In particular, it is a gather time mistake if the majority of the accompanying are valid:

The announcement of a class variable in a class or interface C shows up literarily after an utilization of the class variable;

The utilization is a straightforward name in either a class variable initializer of C or a static initializer of C;

The utilization is not on the left hand side of a task;

C is the deepest class or interface encasing the utilization.

Utilization of occasion variables whose assertions show up literarily after the utilization is now and again confined, despite the fact that these occurrence variables are in degree. In particular, it is an order time mistake if the majority of the accompanying are valid:

The announcement of an occasion variable in a class or interface C shows up literarily after an utilization of the case variable;

The utilization is a straightforward name in either an occasion variable initializer of C or a case initializer of C;

The utilization is not on the left hand side of a task;

C is the deepest class or interface encasing the utilization.

B)

Yes, Forward Reference to nearby names are inside of a solitary strategy.

In the system we need to first announce the varible(local name) strictly when that we can utilize it. Be that as it may, inside of a class Forward Reference to variables are permitted utilizing "this" administrator.

the supporting code is:

public class ScopeTest {

public static void main(String[] args) {
ScopeTest scopeTest = new ScopeTest();
scopeTest.lawfulSameNameVariables(false);
scopeTest.lawfulForwardReferences();
scopeTest.unlawfulForwardReferences();
}
  
/ method is for to two local names are used. /

public void lawfulSameNameVariables(boolean bn) {
boolean isTrue = bn;
if (isTrue == true) {
int n = 1; // 1 is adding to local variable n.
System.out.println("n is " + n);
} else {
int n = 0; // Adds 0 to local variable n.
System.out.println("n is " + n);
}
}
  
/ Forward references are not generally unlawful. /
  
public void unlawfulForwardReferences() {
int n = m; // global variable y is adding to local variable n.
System.out.println("n is " + n);
}
private static int m = 1; // static global variable m.
  
public void unlawfulForwardReferences() {
int m = n; // n is undetermined.then you get compilation error
System.out.println("m is " + m);
}
  
}
