1Z0-811 Java Basics and Syntax Practice Question
Which TWO are valid ways to create a String object?
⚠ Common exam trap
Oracle often tests the distinction between string literals and the new keyword, and the trap here is that candidates may think any use of new is invalid or that a null reference counts as creating an object, but the exam expects you to know that only literals and the String constructor with a String argument are valid ways to create a String object.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
String s = "hello";
Using a string literal ("hello") creates a String object automatically via the JVM's string constant pool, which is a standard and valid way. Option E is correct because the String constructor new String(String) takes another String as an argument, here "hello", which is valid. Option A is incorrect because null is not an object; it is a reference that does not point to any object. Option B is incorrect because the String constructor expects a String or other char sequence, not an int literal. Option D is incorrect because single quotes denote a char literal, not a String.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
String s = null;
Why it's wrong here
Declares reference but does not create an object.
- ✗
String s = new String(10);
Why it's wrong here
No such constructor; expects String or char[] etc.
- ✓
String s = "hello";
Why this is correct
String literal creates a String object.
- ✗
String s = 'hello';
Why it's wrong here
Single quotes are for char, not String.
- ✓
String s = new String("hello");
Why this is correct
Explicit constructor call creates new object.
