You can remove a specific element from a Java array by using the following method:<\/p>\n

    \n
  1. Create a new array and copy all elements from the original array except for the specified position to the new array. The System.arraycopy() method can be used to achieve this.<\/li>\n<\/ol>\n

    For example, let’s say we want to remove an element at the position index:<\/p>\n

    int<\/span>[] originalArray = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\nint<\/span>[] newArray = new<\/span> int<\/span>[originalArray.length - 1<\/span>];\r\n\r\nSystem.arraycopy(originalArray, 0<\/span>, newArray, 0<\/span>, index);\r\nSystem.arraycopy(originalArray, index + 1<\/span>, newArray, index, originalArray.length - index - 1<\/span>);\r\n\r\nfor<\/span> (int<\/span> num : newArray) {\r\n    System.out.print(num + \" \"<\/span>);\r\n}\r\n<\/code><\/pre>\n
    The output result is 1 2 4 5.<\/p>\n
      \n
    1. Delete the element at a specific position using an ArrayList and then convert the ArrayList back into an array.<\/li>\n<\/ol>\n
      import<\/span> java.util.ArrayList;\r\n\r\nint<\/span>[] originalArray = {1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span>};\r\nArrayList<Integer> arrayList = new<\/span> ArrayList<\/span><>();\r\n\r\nfor<\/span> (int<\/span> num : originalArray) {\r\n    arrayList.add(num);\r\n}\r\n\r\nint<\/span> index<\/span> =<\/span> 2<\/span>; \/\/ \u6307\u5b9a\u8981\u5220\u9664\u7684\u4f4d\u7f6e<\/span>\r\narrayList.remove(index);\r\n\r\nint<\/span>[] newArray = new<\/span> int<\/span>[arrayList.size()];\r\n\r\nfor<\/span> (int<\/span> i<\/span> =<\/span> 0<\/span>; i < arrayList.size(); i++) {\r\n    newArray[i] = arrayList.get(i);\r\n}\r\n\r\nfor<\/span> (int<\/span> num : newArray) {\r\n    System.out.print(num + \" \"<\/span>);\r\n}\r\n<\/code><\/pre>\n
      The output will be: 1 2 4 5<\/p>\n","protected":false},"excerpt":{"rendered":"
