There are several ways to define a two-dimensional array in Java.<\/p>\n

    \n
  1. Using static initialization method:<\/li>\n<\/ol>\n

      \n
    1. Initialize using a dynamic method:<\/li>\n<\/ol>\n
      int<\/span>[][] arr = new<\/span> int<\/span>[3<\/span>][3<\/span>];\r\narr[0<\/span>] = new<\/span> int<\/span>[]{1<\/span>, 2<\/span>, 3<\/span>};\r\narr[1<\/span>] = new<\/span> int<\/span>[]{4<\/span>, 5<\/span>, 6<\/span>};\r\narr[2<\/span>] = new<\/span> int<\/span>[]{7<\/span>, 8<\/span>, 9<\/span>};\r\n<\/code><\/pre>\n
        \n
      1. Defining the length of an array.<\/li>\n<\/ol>\n
        int<\/span>[][] arr = new<\/span> int<\/span>[3<\/span>][3<\/span>];\r\n<\/code><\/pre>\n
          \n
        1. Initialization using a for loop:<\/li>\n<\/ol>\n
