The Arrays Class in Java

The java.util.arrays class contains different functions for sorting and seeking values from array, looking at arrays, and filling components into arrays. These functions are available for all primitive data types.

  • public static boolean equals(long[] a, long[] a2) – returns true if the two indicated arrays are equivalent to each other. Two arrays are viewed as equivalent if both of them contain the same number of components, and all relating sets of components in the two arrays are equivalent. This returns true if the two shows are equivalent. Same function could be utilized by all other primitive data types.
  • public static int binarysearch(object[] an, Object key) – looks the pointed out array of Object for the defined value utilizing the double calculation. The array must be sorted before making this call. This returns list of the keys, in the event that it is contained in the list; generally, (-(insertion point + 1).
  • public static void sort(Object[] a) – This function can be used to sort a given arrayin the ascending order. It can likewise be used for any data type.
  • public static void fill(int[] an, int val) – appoints the detailed int value to every component of the pointed out array of ints. Same function could be utilized for arrays of other data types as well.
