Classes and object

Question

I have created a class with two methods both with void return type and no arguments...the first method input the data and the second one has to give the desired output...but how to access variables of method one into method two...

Answer 1

Scope of a variable declared in a method is inside that method only. So, you can't access it in another method.

Answer 2

I already initialized the variable as global and also it worked but the compile time is much more than expected

Answer 3

This is o9 assignments given by our clg just like those at hackerearth or codechef so I have to check for 4 test cases

Answer 4

Can you share the code??

Answer 5

Yeah sure

Answer 6

public static class merge{
int n,m,i,j,count=0;
public void getInput(){
Scanner in=new Scanner(System.in);
n=in.nextInt();
int a[]=new int[n];
for(i=0;i<n;i++){
a[i]=in.nextInt();
}
m=in.nextInt();
int b[]=in.nextInt();
for(i=0;i<m;i++){
b[i]=in.nextInt();
}
}

Answer 7

Now I want to access all this information in a new function for merging into a new array

Answer 8

Utkarsh You are creating these arrays in getInput() method. Reference variables 'a' and 'b' will get destroyed as soon as method gets executed. So, with no reference Arrays will be cleared from memory by garbage collector. You have to declare 'a' and 'b' inside class outside the method.

Answer 9

I already did that and i was getting my answer but then I told you ...it was showing compile time error

Answer 10

So basically there's no other way?
