You can reverse a Java array using the following methods:<\/p>\n

    \n
  1. Use a loop to create a new array, traverse the original array starting from the end, and place the elements into the new array sequentially.<\/li>\n<\/ol>\n
    public<\/span> static<\/span> void<\/span> reverseArray<\/span>(int<\/span>[] arr)<\/span> {\r\n    int<\/span>[] reversedArray = new<\/span> int<\/span>[arr.length];\r\n    \r\n    for<\/span> (int<\/span> i<\/span> =<\/span> 0<\/span>; i < arr.length; i++) {\r\n        reversedArray[i] = arr[arr.length - 1<\/span> - i];\r\n    }\r\n    \r\n    for<\/span> (int<\/span> i<\/span> =<\/span> 0<\/span>; i < arr.length; i++) {\r\n        arr[i] = reversedArray[i];\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Use the Collections.reverse() method: convert the array to a List, and then reverse it using the Collections.reverse() method.<\/li>\n<\/ol>\n
      import<\/span> java.util.Arrays;\r\nimport<\/span> java.util.Collections;\r\n\r\npublic<\/span> static<\/span> void<\/span> reverseArray<\/span>(int<\/span>[] arr)<\/span> {\r\n    Integer[] integerArr = Arrays.stream(arr).boxed().toArray(Integer[]::new<\/span>);\r\n    Collections.reverse(Arrays.asList(integerArr));\r\n    \r\n    for<\/span> (int<\/span> i<\/span> =<\/span> 0<\/span>; i < arr.length; i++) {\r\n        arr[i] = integerArr[i];\r\n    }\r\n}\r\n<\/code><\/pre>\n
      You can use either of these two methods to reverse the array. Just choose one to use.<\/p>\n","protected":false},"excerpt":{"rendered":"
