There are several ways to define arrays in Java.<\/p>\n

    \n
  1. Declare an array variable and allocate memory space for it.<\/li>\n<\/ol>\n
    int<\/span>[] array1 = new<\/span> int<\/span>[5<\/span>];\r\nString[] array2 = new<\/span> String<\/span>[10<\/span>];\r\ndouble<\/span>[] array3 = new<\/span> double<\/span>[3<\/span>];\r\n<\/code><\/pre>\n
      \n
    1. Initialize an array directly.<\/li>\n<\/ol>\n
      int<\/span>[] array1 = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\nString[] array2 = {\"apple\"<\/span>, \"banana\"<\/span>, \"orange\"<\/span>};\r\ndouble<\/span>[] array3 = {1.2<\/span>, 3.4<\/span>, 5.6<\/span>};\r\n<\/code><\/pre>\n
        \n
      1. Create an array using static methods.<\/li>\n<\/ol>\n
        int<\/span>[] array1 = Arrays.copyOf(array2, 5<\/span>);\r\nString[] array2 = Arrays.copyOfRange(array1, 0<\/span>, 3<\/span>);\r\n<\/code><\/pre>\n
          \n
        1. Create an array using the array constructor method.<\/li>\n<\/ol>\n
          int<\/span>[] array1 = new<\/span> int<\/span>[]{1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\nString[] array2 = new<\/span> String<\/span>[]{\"apple\"<\/span>, \"banana\"<\/span>, \"orange\"<\/span>};\r\ndouble<\/span>[] array3 = new<\/span> double<\/span>[]{1.2<\/span>, 3.4<\/span>, 5.6<\/span>};\r\n<\/code><\/pre>\n
            \n
          1. Utilize multidimensional arrays:<\/li>\n<\/ol>\n
            int<\/span>[][] array1 = new<\/span> int<\/span>[3<\/span>][4<\/span>];\r\nString[][] array2 = new<\/span> String<\/span>[2<\/span>][];\r\narray2[0<\/span>] = new<\/span> String<\/span>[3<\/span>];\r\narray2[1<\/span>] = new<\/span> String<\/span>[2<\/span>];\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
