Method capacity

output/java_guava/1.4.16/Maps.java:205–217

Returns a capacity that is sufficient to keep the map from being resized as long as it grows no larger than expectedSize and the load factor is >= its default (0.75).

(int expectedSize)

  static int capacity(int expectedSize) {
    if (expectedSize < 3) {
      checkNonnegative(expectedSize, "expectedSize");
      return expectedSize + 1;
    }
    if (expectedSize < Ints.MAX_POWER_OF_TWO) {
      // This is the calculation used in JDK8 to resize when a putAll
      // happens; it seems to be the most conservative calculation we
      // can make.  0.75 is the default load factor.
      return (int) ((float) expectedSize / 0.75F + 1.0F);
    }
    return Integer.MAX_VALUE; // any large value
  }
