Problem in using BigDecimal values in for Loop

[Nagendra Batchu]

Hi All,

BigDecimal bd5=new BigDecimal("89999999999994552010");
BigDecimal bd6=new BigDecimal("89999999999994552020");

how to iterate it from starting bd5 to end of bd6

for(BigDecimal bd51=bd5;bd5.max(bd6);bd51.add(one)){

}

i had used this which is not working ... could any one help me in solving this problem

try this code:

  
for(BigDecimal bd51=bd5;bd51.compareTo(bd6) <= 0;bd51 = bd51.add(BigDecimal.ONE)){
    System.out.println(bd51);
}  

your code is wrong in multiple ways:

  
for(BigDecimal bd51=bd5;bd5.max(bd6);bd51.add(one)){

} 

1. bd5.max(bd6) returns BigDecimal, it does not compare them, you can compare them with bd51.compareTo(bd6)
2. you cannot use bd5 in the comparison, unless you change bd5 or bd6. Otherwise you end up with infinite loop. Though you can change them inside the body of the loop somewhere, then you good to go with this comparison (remember to use compareTo() , not max())
3. BigDecimal is immutable, so bd51.add(BigDecimal.ONE) returns new BigDecimal, but does not change the bd51 unless you assign it a new value yourself.

You should only use integer numbers as the counter in a for loop. I presume this example was justified under the heading of "I just wanted to see what happens if . . ."
