java - For loop inside of for loop not executing -

the second loop executing first number(999) in first loop. trying have second loop execute each number 999-101 in second.

int num1 = 999; int num2 = 999; int test1 = 0; string test = "";  for(; num1!=110; num1--){     system.out.println("--------"+num1);     for(; num2!=100; num2--){         system.out.println("++++++++"+num2);         test1 = num1*num2;          test = string.valueof(test1);         //system.out.println("checkpoint 2"+"--------------"+test1);         if(test.length()==5){             if(test.charat(0)==test.charat(5) && test.charat(1)==test.charat(4) && test.charat(2)==test.charat(3)){                 system.out.println("checkpoint 1"+"----------"+test);                 break;             }             else{                 //system.out.println("fail 1");             }         }     } } 

after first run of second loop num2 has value 100 statement num2!=100 false , not execute. set value num2 execute each loop:

for(num2=999; num2!=100; num2--) {   ... }
