Description
StringBuffers and StringBuilders have the potential to grow significantly, which could lead to memory leaks if they are retained within objects with extended lifetimes.
Non-Compliant Code Examples
public class Foo {
private StringBuffer buffer1; // potential memory leak as an instance variable;
private String buffer2;
private StringBuilder buffer3; // potential memory leak as an instance variable;
}
Compliant Code Examples
public class Foo {
public void method() {
StringBuffer buffer;
}
}
