What is the correct syntax to declare a variable in Java?Points:1x = 5;variable x;None of the aboveint x;I don't know

Break Down the Problem

1. Identify the options given for declaring a variable in Java.
2. Determine which option adheres to the Java syntax rules for variable declaration.

Relevant Concepts

• In Java, a variable must be declared with a data type followed by the variable name. For example, int x; is the proper syntax where int is the data type and x is the variable name.

Analysis and Detail

1. Option 1: x = 5; - This is an assignment statement, not a declaration.
2. Option 2: variable x; - This is not a valid declaration because "variable" is not a data type in Java.
3. Option 3: None of the above - This would be correct if none of the options were valid.
4. Option 4: int x; - This is the correct way to declare an integer variable named x.
5. Option 5: I don't know - This does not provide a valid declaration.

Verify and Summarize

The only valid declaration from the options provided is int x;.

Final Answer

The correct syntax to declare a variable in Java is int x;.
