Test 1
boolean hasPassedTest = true;Given two int variables , i and j, which have been declared and initialized , and two other int variables , itemp and jtemp, which have been declared , write some code that swaps the values in i and j by copying their values to itemp and jtemp respectively, and thencopying itemp and jtemp to j and i respectively.itemp = i;jtemp = j;i = jtemp;j = itemp;Given three already declared int variables , i, j, and temp, write some code that swaps the values in i and j. Use temp to hold thevalue of i and then assign j‘s value to i. The original value of i, which was saved in temp, can now be assigned to j.temp = i;i = j;j = temp;Given two int variables , firstPlaceWinner and secondPlaceWinner, write some code that swaps their values . Declare any additionalvariables as necessary.int swap_me = firstPlaceWinner;firstPlaceWinner = secondPlaceWinner;secondPlaceWinner = swap_me;Given two double variables , bestValue and secondBestValue, write some code that swaps their values . Declare any additionalvariables as necessary.double tempNum;tempNum = bestValue;bestValue = secondBestValue;secondBestValue = tempNum;Four integer variables , pos1, pos2, pos3, pos4 have been declared and initialized . Write the code necessary to “left rotate” theirvalues : for each variable to get the value of the successive variable , with pos4 getting pos1’s value .int tempP1 = pos1; int tempP2 = pos2; int tempP3 = pos3; int tempP4 = pos4; pos4 = tempP1; pos3 = tempP4; pos2 = tempP3; pos1 = tempP2;Declare a variable populationChange, suitable for holding numbers like -593142 and 8930522.int populationChange;Declare a variable x, suitable for storing values like 3.14159 and 6.02E23.float x;Declare a variable temperature and initialize it to 98.6.
