    Cool What is >>> with -4?

    In jadx I see the code
    int i14 = (i11 >>> (-16)) | (i11 << 16);

    I thought the decompiler wrong do. But in smali code is the same one.


    ushr-int/lit8 v0, v0, -0x10

    Can somebody from you explain to me what doing this expression? And how it to short.

    Look at some examples for the >>> operator: https://www.geeksforgeeks.org/bitwis...ators-in-java/

    Use the Integer class's toBinaryString method to print out intermediate results in binary.
       System.out.println(Integer.toBinaryString(i11 >>> (-16)));
    If you don't understand my answer, don't ignore it, ask a question.
