Qual a diferenca entre wait(), notify(), notifyAll();   Alguem pode me explicar : << Un-signed left shift >> Signed right shift >>> Un-signed right shift public class TestShift {        public static void main(String args[]) {                int x = 1;                x = x >> 31;                int y = -1;                y = y >> 31;                System.out.println("The ouput of x is " + x );                System.out.println("The ouput of y is " + y );        } }   public class TestShift {       public static void main(String args[]) {                int x = 1;                x = x << 31;                int y = -1;                y = y << 31;                System.out.println("The output of x is " + x );                System.out.println("The output of y is " + y );        } }   public class TestShift {        public static void main(String args[]) {                int x = 1;                x = x >>> 31;                int y = -1;                y = y >>> 31;                System.out.println("The output of x is " + x );                System.out.println("The output of y is " + y );        } }
