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";

A string literal, which is a valid way to create a String object. Option D uses the String constructor with a string argument, also valid. Option B assigns an integer literal to a String variable, which is not allowed. Option C attempts to cast an Integer object to String, which causes a compile-time error because Integer is not a subclass of String. Option E uses a char literal ('Hello' is invalid because char literals are single characters) and is not assignable to 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 = "Hello";
Why this is correct
String literal, directly assigned to String variable. This is valid because string literals are instances of String.
✗
String s = 12345;
Why it's wrong here
Cannot assign an integer literal to a String variable. Type mismatch.
✗
String s = (String) new Integer(10);
Why it's wrong here
Attempts to cast an Integer object to String, which causes a compile-time error because Integer is not a subclass of String.
✓
String s = new String("Hello");
Why this is correct
Creating a String object via the String constructor with a string argument. Valid.
✗
String s = 'Hello';
Why it's wrong here
Uses a char literal 'Hello', but char literals are single characters, so 'Hello' is invalid and not assignable to String.
