&gt;&gt; is arithmetic shift right or Signed right shift
For example: -2 represented in 8 bits would be 11111110 (because the most significant bit has negative weight). Shifting it right one bit using arithmetic shift would give you 11111111, or -1.
&gt;&gt;&gt; is logical shift right or Unsigned right shift 
Logical right shift, however, does not care that the value could possibly represent a signed number; it simply moves everything to the right and fills in from the left with 0s. Shifting our -2 right one bit using logical shift would give 01111111
<pre><code>jshell&gt; int x = -1;
x ==&gt; -1

jshell&gt; int y = x&gt;&gt;&gt;1;
y ==&gt; 2147483647

jshell&gt; int z = y &gt;&gt;&gt;1;
z ==&gt; 1073741823

jshell&gt; int x = -1;
x ==&gt; -1

jshell&gt; int y = x&gt;&gt;1;
y ==&gt; -1

jshell&gt; int z = y&gt;&gt;1;
z ==&gt; -1
