Activity jumps and passes values. Mainly through the intent class. The role of intent is to activate the component and the accompanying data.First, activity jumpsMethod OneIntent Intent = new Intent (a.this, B.class);StartActivity (Intent)Method TwoIntent Intent = new Intent ();Intent.setclass (A.this, B.class);StartActivity (Intent);Implementation from a jump to B (A, B are inherited from activity)II. Transmission of dataActivity A transmits dataMethod OneIntent Intent = new Intent ();Intent.se
In general, the basic data types are passed to the method, and when you pass an array to a method, you need to consider the allocation of memory Public classTest2 { Public Static voidMain (String args[]) {intArr[] =New int[] {9,1,2,3,4,7,8,6,5 }; Sort (arr); for(intI=0; i) {System. out. println (Arr[i]); } } Public Static voidSortintArr[]) {//Bubble Sort for(intx=0; x) { for(inty=0; y1; y++) { if(Arr[y] > arr[y+1]) { inttem
