Examples of java.util.ArrayList.ensureCapacity()

java.util.ArrayList.ensureCapacity()
Increases the capacity of this ArrayList instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument. @param minCapacity the desired minimum capacity

    try {
      al.ensureCapacity(capacity);
      assertTrue("EnsureCapacity moved objects around in array1.",
          location == al.indexOf(testObject));
      al.remove(0);
      al.ensureCapacity(capacity);
      assertTrue("EnsureCapacity moved objects around in array2.",
          --location == al.indexOf(testObject));
      al.ensureCapacity(capacity + 2);
      assertTrue("EnsureCapacity did not change location.",
          location == al.indexOf(testObject));
