Find and Replace Code Duplicates
The Find and Replace Code Duplicates action allows you to find code repetitions similar to the selected method or constant field, and replace them with calls to the original method or constant.
Example
| Before | After |
|---|---|
public void method() {
int a = 1;
int b = 2;
int c = a+b;
int d = b+c;
}
...
private int add(int a, int b) {
return a+b;
} | public void method() {
int a = 1;
int b = 2;
int c = add(a,b);
int d = add(b,c);
}
...
private int add(int a, int b) {
return a+b;
} |
