예제

public class ClassA {
private final StringBuffer stringObject = new StringBuffer("A new String");
private StringBuffer nonConstantString = new StringBuffer("Changing String");

public void method() {
StringBuffer localString;
final StringBuffer localConstantString;
}
}

솔루션

대신 상수(final) StringBuffer 오브젝트는 String을 사용하여 선언하십시오.

public class ClassA {
private final String stringObject = "A new String";
private StringBuffer nonConstantString = new StringBuffer("Changing String");

public void method() {
StringBuffer localString;
final String localConstantString;
}
}
