Is “return” statement in java have implicit break?

Example :

public Boolean deleteCarrier(String carrierCode, Carrier[] carrierArray) {
for(int i=0;i<carrierArray.length;i++){
for(int j=1;j<carrierArray.length-1;j++){

    if (carrierArray[j]==null){                     
    return true;                        

return false;

does this code comes out of the loop once the condition is satisfied ?. Do "return" have implicit break ?

Return will exit the immediately, so yes. If the code executed a return statement there wouldn't be further iteration of the loop.

You can use Break and then use Return or you can just Return like you have.
