Will it be same?

Thanks..My problem is resolved

no, valueOf and autoboxing trigger caching (static Integer objects already initialized inside the Integer class for values form -128 to 127) while the constructor always creates a new instance. In addition to that the constructor is deprecated since 9.

Integer a = 10; // autoboxing, caching
Integer b = Integer.valueOf(10); // caching
Integer c = new Integer(10); // no caching
Integer d = new Integer(10);

System.out.println(a == b); // true, cached versions pointing to the same instance
System.out.println(a == c); // false, c is a new instance
System.out.println(c == d); // false
