Place Stack Trace into a String in Java
In order to place stack trace into a String in Java, we use the java.io.StringWriter and java.io.PrintWriter classes. In a catch block, after catching the exception, we print the stack trace by printStackTrace() method and write it into the writer and then use the ToString() method to convert it into a String.
Let us see a program to place the stack trace into a String in Java.
Example
import java.io.PrintWriter;
import java.io.StringWriter;
public class Example {
public static void main(String[] args) {
try{
int ans = 10/0;
}catch (ArithmeticException ex) {
StringWriter s= new StringWriter();
ex.printStackTrace(new PrintWriter(s)); // writing the stack trace in the writer
String str = s.toString(); // converting it into a String
System.out.println(str);
}
}
}Output
java.lang.ArithmeticException: / by zero at Example.main(Example.java:8)
