为啥我写的java程序在输入数据很小时可以得出正常结果，大了就不行呢？

Question

import java.util.Scanner;
public class test {
    public static String decimalToBinary(int value) {
       long  binary=0;
               int i=0,j;
        long binaries[];
        binaries=new long[100000];
        while(value!=0)
        {
            binaries[i]=value%2;
            value/=2;
            i++;
        }
        for(j=i-1;j>=0;j--)
        {
            binary+= binaries[j]*(int) Math.pow(10,j);
        }
        System.out.println(binary);
        return Long.toString(binary);
    }
public static  void main(String[] args){
    while(true){
int i=1000000000;
System.out.println(i);
        System.out.print("Enter an integer");
    Scanner s=new Scanner(System.in);
    int num=s.nextInt();
    System.out.println("The binary value is"+decimalToBinary(num));}
}
}
如上，求问大佬
