question about JAVA(how to increment a result?)

Question

for example
int a = 1165;
System.out.println(Math.sqrt(a));

the answer is 34 from console,then i wanna increment this reasult or work on this result directly,
without bringing another variable and giving a value of the result like this [ int b=34;
System.out.println(++b); ]

Answer 1

You can assign the result back to the same variable.

int a = 1165;
a = (int)Math.sqrt(a);
System.out.print(++a);

Answer 2
