}

From source file:Main.java

public static void main(String[] args) {
    StringBuilder sb = new StringBuilder(200); // Capacity:200, length:0

}

From source file:Main.java

    // using clone to affect the objects pointed to by the references.
    ArrayList arrlist2 = (ArrayList) arrlist1.clone();

    // appending the string
