In Java, you can create and initialize arrays in the following way:<\/p>\n

    \n
  1. Initialize an array using an array literal, meaning providing initial values at the time of creating the array. For example:<\/li>\n<\/ol>\n
    int<\/span>[] numbers = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>}; \/\/ \u521b\u5efa\u4e00\u4e2a\u5305\u542b5\u4e2a\u6574\u6570\u7684\u6570\u7ec4\uff0c\u5e76\u521d\u59cb\u5316\u4e3a1, 2, 3, 4, 5<\/span>\r\nString[] names = {\"Alice\"<\/span>, \"Bob\"<\/span>, \"Charlie\"<\/span>}; \/\/ \u521b\u5efa\u4e00\u4e2a\u5305\u542b3\u4e2a\u5b57\u7b26\u4e32\u7684\u6570\u7ec4\uff0c\u5e76\u521d\u59cb\u5316\u4e3a\"Alice\", \"Bob\", \"Charlie\"<\/span>\r\n<\/code><\/pre>\n
