Syntax Error

Incompatible types: int cannot be converted to String

What This Error Means

This error occurs when you are trying to assign a value of one data type to a variable that is declared with a different data type.

Why It Happens

This error happens because Java is a statically-typed language, meaning it checks the data types at compile time. When you try to assign an int value to a String variable, Java throws a syntax error because it knows that the value can't be converted.

How to Fix It

  1. 1To fix this error, you need to assign the correct data type to the variable or use a method that can convert the value to the desired data type. For example, you can use the String.valueOf() method to convert an int to a String.

Example Code Solution

❌ Before (problematic code)
Java
String name = 123;
✅ After (fixed code)
Java
String name = String.valueOf(123);
