NullPointerException at line 73 in helloworld.java
.
Possible Solutions:
Check for null values: Ensure that the variable you are accessing on line 73 is not null before attempting to use it. Use an if
statement or a null-safe operator (like the Elvis operator ?:
in Java) to handle potential nulls.
Initialize variables: Make sure all variables used in the code, particularly on line 73, are properly initialized before they are accessed.
Inspect the surrounding code: Review the code in the helloworld.java
file, specifically the lines leading up to line 73, to identify any potential causes for the null value.
Debugger: Use a debugger to step through the code and inspect the variables at runtime. This can help pinpoint the exact location where the null value is being assigned.
