public ArrayTool()

Method Detail

contains

public static int contains(Object[] container,
                           Object within)

Test if a given object is within the array. Uses the equals method of the object. Returns the index of the matching object or -1.

equalInts

public static boolean equalInts(int[] size)

Tests, if an integer array has all equal numbers. Use this to check multiple lists for equal size in ArrayTool.equalInts(new int[]{list1.size(), list2.size(),...})

Returns:

True, if array is null or all elements have the same value.

minmax

public static double[] minmax(double[] in)

Scans the primitve array for the minimum and maximum value.

minMax

public static Vector2D minMax(double[] in)

Scans the primitve array for the minimum and maximum value, returns it as a vector2d

toDouble

public static double[] toDouble(float[] f)

Converts a float[] to a double[]
