在最外面的循环上使用标签，
break当您想跳出所有循环时，可以在语句中包括该标签。在下面的示例中，我修改了您的代码以使用标签
OUTERMOST：
String valueFromObj2 = null;String valueFromObj4 = null;OUTERMOST: for(Object1 object1: objects){ for(Object2 object2: object1){ //I get some value from object2 valueFromObj2 = object2.getSomevalue(); for(Object3 object3 : object2){ for(Object4 object4: object3){ //Finally I get some value from Object4. valueFromObj4 = object4.getSomevalue(); //Compare with valueFromObj2 to decide either to break all the foreach loop if( compareTwoVariable(valueFromObj2, valueFromObj4 )) { break OUTERMOST; } }//fourth loop ends here }//third loop ends here }//second loop ends here}//first loop ends here
