=== Code examples

==== Noncompliant code example

[source,java,diff-id=1,diff-type=noncompliant]
----
int foo(int y) {
  int x = 100; // Noncompliant: dead store
  x = 150;     // Noncompliant: dead store
  x = 200;
  return x + y;
}
----

==== Compliant solution

[source,java,diff-id=1,diff-type=compliant]
----
int foo(int y) {
  int x = 200; // Compliant: no unnecessary assignment
  return x + y;
}
----
