To run the javac compiler with the -Xlint option, you will need to have the Java Development Kit (JDK) installed on your computer. The javac compiler is included in the JDK and is used to compile Java source code into Java bytecode.
To run javac with the -Xlint option, you can use the following command:
javac -Xlint:<warning> [source files]
Replace <warning> with the type of warning that you want to enable. For example, you can use all to enable all warnings, or you can specify a specific warning such as unchecked to enable only that warning.
For example, to compile a Java source file MyProgram.java with all warnings enabled, you can use the following command:
javac -Xlint:all MyProgram.java
This will compile MyProgram.java and any warnings will be displayed in the Command Prompt.
